Fix language-map.json build script

[zm-cttae]

• Search for extension manifests in microsoft/vscode instead of microsoft (half the manifests, more languages).
• Add logic to try match contributed filenames/extensions to their icon using the existing icon map.
• Abstract the icon name logic in the build script.

Test case:

• v1.7.3 will throw an error in processLanguageContribution because lang isn't reassigned back
• https://github.com/microsoft/vscode/blob/1.74.0/extensions/shellscript/package.json#L28-L69
  Once fixed and run, any matches to console will disappear in language-map.json

• In PR Add language config mappings from VSC extensions #10 it was decided to keep this extension lean and rely on the icon pack
• But that PR added a remap/overrides JSON (e.g. to make *.npmrc use npm icon)
• The overrides mostly don't make sense e.g. stops the settings and properties icons from appearing on generic ignore/setup files
  For example, test.gitconfig gets the git icon but doesn't apply any configuration in git

Can I remove those overrides from build-languages.js and then uncheck language-map.json, remap.json?

I went ahead and removed it in 866254f.

@zm-cttae I know I'm already a couple of months late but just wanted to bump this PR so you see that I saw it. I will need to dig a little bit into what these changes would mean so it'll take me a little bit to have a proper review but overall I'm not against these changes.

[zm-cttae]

Cool. The big change is #49 (comment) which brings us closer to the upstream extension in behaviour
