Rename *Literal nodes to *LiteralExpression

[MichaReiser]

Summary

#1799 introduced a new JsLiteralMemberName that is defined as JsLiteralMemberName = value: ('ident' | 'js_string_literal_token' | 'js_number_literal_token'). That means, quering for all StringLiterals using root.descendants().filter(JsStringLiteral::cast) will not return the string_literal_token inside of the JsLiteralMemberName.

This is expected, because the JsLiteralMemberName contains the token and not the JsStringLiteral node but it may be unexpected for pass authors.

I believe that not using a JsStringLiteral inside of member names or import statements (module name) is desired because authors may otherwise be inclined to, for example, replace all JsStringLiteral with JsTemplateLiteralExpression but that will create an invalid syntax tree in the case of import statements.

That's why this PR renames Js*Literals to Js*LiteralExpression to make it clear that these are the literal expressions. It then renames JS_*_LITERAL_TOKEN to JS_*_LITERAL as we no longer need the token postfix to avoid the name collision.

The PR does not change the parsing for PropName since this will go away soon anyway.

Test Plan

Verified the changes rast outputs to make sure the parser changes were correctly applied.

@MichaReiser as you can see the CI is not triggering any action. I think you should add feature/member-expression branch to the CI.

I think we should come up with a naming convention for branches that will require multiple PRs and still triggering the CI (myself and yourself are doing this).

Something like multiple-feature/* and branches like this will trigger the CI too (not just main).

[MichaReiser]

The CI job will run when the base branch is merged.

That's the thing. The CI is not running here and there's now way for reviewers to see if these new changes are healthy or not. What if the coverage goes down? Lint issues?
