Add support for Paket

[xt0rted]

Checklist:

• If this PR is a new feature, please provide at least one example link
• Make sure all of the significant new logic is covered by tests

This adds support for the f#/.net package manager Paket. I didn't add support for paket.lock files because we don't really support them for other environments.

Example files used when building this out:

• https://github.com/fsprojects/Paket/blob/master/paket.dependencies
• https://github.com/fsharp/TryFSharp/blob/d2d4b6bee9d5b6a232c3e902f5af06eb460e3419/paket.dependencies
• https://github.com/fsprojects/Paket/blob/master/src/Paket/paket.references
• https://github.com/simontaite/EFCore.FSharp.MigrationTest/blob/ae0a7c97379ea4958bd75ebcf861fcf81538af6f/paket.local

Some of my files have been using CrLf. The setting in .gitattributes doesn't cover new files so I think VS Code's been using the system default which this will fix.

@stefanbuck for some reason a bunch of unrelated tests keep failing on this and #1035

[stefanbuck]

From what I can tell, tests are failing because your branch is behind the main branch by 22 commits. All failing tests are related to recently added features like css and PHP which are missing on your branch. Still confusing, because the config for E2E tests is generated on the fly by walking through the fixtures folder.

Ohh looks like the checkout step is doing a merge https://github.com/OctoLinker/OctoLinker/pull/1047/checks?check_run_id=1200633923#step:3:357 I'm going to rebase your branch to verify my assumption

[stefanbuck]

Oh dear, something went wrong while rebasing. @xt0rted please rebase and push the branch again. Sorry for the mess
