preemptively download wasm plugins

[nhomble]

The github outage yesterday elucidated our dependencies on external systems in our CI environment. We are already using the env variable described in: https://moonrepo.dev/blog/moon-v1.16#force-toolchain-to-use-global-binaries

MOON_TOOLCHAIN_FORCE_GLOBALS

However, the blog mentions an exception for these plugins

Disable downloading and installing tools (will still download the WASM plugins).

Indeed, we saw this error during the outage

Error: net::download_failed
  × Failed to download file from https://github.com/moonrepo/plugins/releases/
  │ download/typescript_toolchain-v0.2.0/typescript_toolchain.wasm (500
  │ Internal Server Error).

Are there any configurations or setup we can do in our ci images to remove these external downloads during runtime?

@nhomble There is now way to disable downloading plugins, since they are required for specific functionality, and moving forward, more and more of moon will be plugin based.

The only work around for this is to prime the plugin cache and persist it across runs.
