Set up typing on console.fontLigatures and console.fontVariations so it is the same as the editor counterparts (#10928)

Addresses #10593

This PR makes the typing for the new `console.fontLigatures` and
`console.fontVariations` settings the same as what we inherited for
`editor.fontLigatures` and `editor.fontVariations`, since that is how
these settings actually work. This does not change how these settings
function but now the hinting in `settings.json` is correct:

/>


### Release Notes

#### New Features

- N/A

#### Bug Fixes

- Fixed typing for Positron's `console.fontLigatures` setting


### QA Notes

If you use a setting like `"console.fontLigatures": "'ss05'"` you should
get no errors and the same hinting that you would get for
`"editor.fontLigatures": "'ss05'"`.
