Add PIO Syntax

[patopesto]

• I'm the package's author and/or maintainer.
• I have have read the docs.
• I have tagged a release with a semver version number.
• My package repo has a description and a README describing what it's for and how to use it.
• My package doesn't add context menu entries. *
• My package doesn't add key bindings. **
• Any commands are available via the command palette.
• Preferences and keybindings (if any) are listed in the menu and the command palette, and open in split view.
• If my package is a syntax it doesn't also add a color scheme. ***
• If my package is a syntax it is named after the language it supports (without suffixes like "syntax" or "highlighting").
• I use .gitattributes to exclude files from the package: images, test files, sublime-project/workspace.

My package is a syntax for the PIO assembly language found on RPI Pico controllers.

There are no packages like it in Package Control.

Not sure I fully understand why the trigger-review CI job failed. Any help would be appreciated.

There seems to be an issue with tests and GitLab hosted packages. Your work looks good though, so I think we can just ignore that.

One thing though, your syntax requires a reasonably recent version of ST, so please set the version requirements to "sublime_text": ">=4107".
