Add support for MiniScript

[ayecue]

From the MiniScript manual:

MiniScript is a modern scripting language designed to be clean, simple, and easy to learn. It
was designed from the ground up by borrowing only the best ideas from other languages
such as Python, Lua, Basic, and C#. If you know pretty much any other programming
language, you’ll pick up MiniScript almost immediately.

And if you’ve never written a line of code in your life, don’t panic! MiniScript is the
friendliest and most fun way to get started. It’s much easier than you probably expect.

Important: MiniScript is designed as an embedded programming language. That means
you will usually use it inside some other program, such as a video game. You should find
another document that describes how to access and use MiniScript within that other
program. This document only describes the MiniScript language itself, and the intrinsic
functions that are common to most MiniScript applications.

Following changes are performed in this PR:

• add MiniScript entry to languages.yml
• add MiniScript samples from https://github.com/JoeStrout/miniscript repo
• add MiniScript grammar from https://github.com/ayecue/miniscript-textmate-linguist
• add heuristics related to the file extension .ms

Checklist:

• I am adding a new language.
  • The extension of the new language is used in hundreds of repositories on GitHub.com.
    • Search results for each extension:
      • https://github.com/search?type=code&q=NOT+is%3Afork+path%3A*.ms+%2F%5E%5Cs*%5Cbend+%28%3F%3Afunction%7Cwhile%7Cif%7Cfor%29%5Cb%7C%5Cs%5Cb%28%3F%3Aisa%29%5Cb%5Cs%2F
  • I have included a real-world usage sample for all extensions added in this PR:
    • Sample source(s):
      • https://github.com/JoeStrout/miniscript/tree/master/MiniScript-cpp/demo
    • Sample license(s):
      • https://github.com/JoeStrout/miniscript/blob/master/LICENSE
  • I have included a syntax highlighting grammar: https://github.com/ayecue/miniscript-textmate-linguist
  • I have added a color
    • Hex value: #494247
    • Rationale: Color of the fur of the MiniScript mascot.
  • I have updated the heuristics to distinguish my language from others using the same extension.

samples/MiniScript/superstartrek.ms and samples/MiniScript/textAdventure.ms are way too big for our needs - if the diff suppresses the content, it's too big. Please remove them.

Please also update the search query in the PR template to use your heuristics so we can assess popularity and your heuristics.

Done. Both large MiniScript samples have been removed.

Please also update the search query in the PR template to use your heuristics so we can assess popularity and your heuristics.

I've updated the query to include some of the keywords and special variables. While it might not catch every single MiniScript related file, it should cover the majority.

You can use regex in GitHub's search too.

I've reduced the complexity of the heuristics pattern significantly now. Mainly relying on the end block keyword. Additionally I added two more extensions since those should also be relevant to MiniScript.

Commenting mainly to get notifications on this issue (I can't find a Subscribe or Watch button). But just to be sure I understand:

With the Pending Popularity tag, this issue is on hold until we cross some threshold? Is it for this search to return 2000 files, or something else?

Essentially, yes. More deets in #5756

[EntitySeaker]

Is it possible for this pr to get accepted before the 2000 files mark, or is that a hard requirement?

[lildude]

Hard requirement. If we make an exception for one there's no point having the restriction and we'd have no choice but to accept every submission, even for hobby languages that no one uses.
