Omit spaces after https in jsdoc comments

Omit spaces after https in jsdoc comments for tags with names.

Fixes #42581

I experimented with a more comprehensive change that made the parser retain all spaces and moved the responsibility to insert (or omit) the space to the language service. But it would have required another parser change to distinguish initial newlines, plus some too-clever code in the language service to handle initial newlines.

I noticed that #42581 doesn't ask for for whitespace-perfect comment preservation in the compiler API, just no spaces after http in the @see tag, so I decided to make an ad-hoc fix.

This feels super kludgy to me, but I guess if it ends up mattering, you can come back to the parser change.

I agree, but switching the processing of comment whitespace from the parser to the language service is a big change -- I forgot to mention the margin/offside handling would have to move too -- and it would break anybody using the compiler API to get the comment text, since they're expecting processed, not raw, comment text. An API break like that would need to until Typescript 5.0 for sure. 🚎
