Support GHES Base URI in LanguageService

[chirag-ghosh]

languageservices/languageservice/src/action.ts

Lines 70 to 71 in 7c0bffb

	// TODO: Support base uri for GHES
	const gitHubBaseUri = "https://www.github.com/";

The base uri is hardcoded in this file. As a result, any action reference link always gets redirected to github.com. Since the LanguageServer already takes gitHubApiUrl, it leads to a wierd situation where GHES hosted action metadata is being fetched corrctly but the redirect url is wrong.

Is there any roadmap on this fix since this is a TODO item?
