Commit lookup

[flatcap]

Add a new lookup for commits to the neomutt repo.

neo-bot could listen for #[0-9a-fA-F]{7,40}$
The # at the beginning would prevent false positives from words like 'defaced'.

Output format:

📝 Commit 852f9878b by @flatcap "rename OpMain/MENU_MAIN" (6📄/+400/-128) 2022-01-25
   https://github.com/neomutt/neomutt/commit/852f9878b458253bf500f842620a42cdb971a566

Contents:

• Icon 📝
• Leader: Commit
• Commit hash
• Login name of author
• Quoted title of the commit
• Diff stats
  • Number of files changed + icon 📄
  • + + number of lines added
  • - + number of lines removed
• Short commit date
• Link to commit on new line (indented to align text)

This GraphQL will search for a commit by its hash or tag.
(and get a lot of the info we need)

As the trigger is different from Issues, we could have a separate query for it.
(or merge it with the others and put the load on GitHub ;-)
