Shows icons that are omitted from GitHub action branding

[DenverCoder1]

Cool project, I came across this when looking to try out some icons, but I noticed the project includes icons that are not allowed by GitHub which makes the project a bit more difficult to use.

From https://docs.github.com/en/actions/creating-actions/metadata-syntax-for-github-actions#brandingicon:

Brand icons are omitted as well as the following:
coffee columns divide-circle divide-square divide frown hexagon key meh mouse-pointer smile tool x-octagon

Possible solutions

One possibility could be to parse the JSON schema from https://json.schemastore.org/github-action.json to check that the icons are allowed in GitHub actions.
A list appears to be maintained at that link and can be extracted with the query $.properties.branding.properties.icon.enum.

Alternatively, a list could be maintained independently which would probably be faster but potentially more effort to maintain. The list above can of course be omitted, as well as most icons tagged with "logo", the "target" icon seems to be the only exception as far as I can tell.

In case it helps, here is a list formed from taking the difference between the feathericons repo list and the enum appearing in the action schema:

[
    "chrome",
    "codepen",
    "codesandbox",
    "coffee",
    "columns",
    "divide-circle",
    "divide-square",
    "divide",
    "dribbble",
    "figma",
    "framer",
    "frown",
    "github",
    "gitlab",
    "hexagon",
    "instagram",
    "key",
    "linkedin",
    "meh",
    "mouse-pointer",
    "pen-tool",
    "slack",
    "smile",
    "table",
    "tool",
    "trello",
    "twitch",
    "twitter",
    "x-octagon",
    "youtube",
]
