[Feature Request] Add 'Ignore Rule' options to Quick Fix menu

[BinToss]

• Ignore Rule (Workspace)
• Ignore Rule (User)

This has been on my list, but I have not done it so far because there would ideally also be options to update .markdownlint.json (or one of its variants) and it's less clear how to expose all those choices in a way that's not confusing. In my opinion, this should be the preferred approach because it is supported by the two CLI's - but it's also the least clear how to design.

Se also #224 for the suggestion to disable just for the particular line via markdownlint-disable-line.

Also, instead of trying to decide whether to add exclusions in user or workspace or file configuration or whatever, consider using a markdownlint-disable-file inline comment. (Be sure to look for an existing one and update that if possible.)
