set up github actions for easier contribution

[0xa3k5]

I've tried to build this myself, but I couldn't succeed.

There is a script add-icons which accepts a string as the second parameter and runs validation checks, finds matching rawdata and updates the relevant metadata.json with the correct object structure.

The github action should be triggered on:

• pull_request
• push to main
• pull_request_target (to enable prs from forks)

and then should:

• compared the committed changes in packages/core/src/raw-svgs/ with the last commit of main and pass the modified or newly added paths to the add-icons script:

bun run add-icons {{SVG_PATHS}}

afterwards the action should build the packages

bun run build --filter=@token-icons/react --filter=@token-icons/core

write a commit message with the newly added svgs and commit to the trigger (to pull request or directly to the main brach)

the draft version of this action can be found under icon-add.yml
