feat: support non-indented cases in Scala3 match expression

[susliko]

Addresses #264

[susliko]

Should non_indented_cases be aliased to indented_cases here to preserve compatibility for any queries that may not expect nodes other than case_block/indented_cases, wdyt?

+1 to this.

Looks like CI ran against an old version, without changes in grammar.js. Strange 🤔

[susliko]

Changes here and below are caused by changes in the behavior of tree-sitter test -u, which now removes trailing spaces

Previously, we were running generate explicitly only on Linux, but at some point CI started testing on macOS as well? I fixed the CI in #437

LGTM

I guess PREC.right adds to the complexity a bit? I'm ok with bumping this up.

While working on this PR, I realized that the conflict between $.match_expression and $._block is slowing down the generation process by about 9 times. I haven't found a good solution yet, so I'm going to close the PR for now.
