ci(nvim-ts): update paths to refactor

Problem: After https://github.com/tree-sitter/tree-sitter/pull/4496, the
crater tests from nvim-treesitter no longer run on PRs with relevant changes.

Solution: Update the paths in the workflows to the new structure.

Also throttle the build step to 10 parallel tasks (reduces flakiness on
Windows).

Also raise the timeout limit to 30 minutes (it's more expensive to have
to restart flaky tests than to let them run).
