Bump ruby-lsp dependencies to fix crash with Ruby master

After ruby/ruby#15825, `tsort` becomes a bundled
gem and projects using it must declare it as a dependency.

`rbs`, which is a dependency of `ruby-lsp`, only added `tsort` in its
4.0 releases. So this change bumps ruby-lsp's dependencies, specifically
rbs, to 4.0.
