Editorconfig fixes

[cornfeedhobo]

Description

• fix wildcards to include nested files (see the format docs)
• include test/run in the bash section

Motivation and Context

• I noticed that my personal editorconfig was taking over because the wildcards
• I'm playing around with a new approach to running tests, and noticed test/run not respecting editorconfig styles
