Long filepath issue on Windows

[alexeagle]

A TODO for this was introduced in #48

https://github.com/bazel-contrib/rules_ruby/pull/48/files#diff-b803fcb7f17ed9235f1e5cb1fcd2f5d3b2838429d4368ae4c57ce4436577f03fR48

Try removing the exclusion and see if there's a way to fix it.

It looks like an upstream issue, can be worked around on CI by using really short output_base like D:/b:

rules_ruby/.github/workflows/ci.yml

Lines 67 to 68 in 0a2d57b

	# Workaround for long path issues: https://github.com/jruby/jruby/issues/3995.
	output-base: ${{ matrix.os == 'windows-latest' && 'D:/b' || '' }}
