Add Gleam to SUPPORTED_LANGUAGES.md

[maxdeviant]

This PR adds Gleam to the list of supported languages.

The grammar repo is available at gleam-lang/gleam-highlight.js.

Changes

Added an entry for Gleam in SUPPORTED_LANGUAGES.md.

Checklist

• Added markup tests, or they don't apply here because... this is a docs-only change
• Updated the changelog at CHANGES.md

[joshgoebel]

Please also include the dist folder (see 3rd party contributor docs) so users have a standard CJS/auto-register version of the grammar they can drop in if they are still using CJS. This need will disappear with v12, but while the core library is available in both CJS and ES6 module this makes sense.
