choose lsp implementation based upon file path

[mountainpath9]

I have a repo with the following structure

deno.json
package.json
deno/src/**/*.ts                           # needs deno lsp
ts/src/**/*.ts                             # needs nodets lsp

and want to create a .helix/languages.toml file such that the appropriate lsp is started depending on the opened typescript file.

It seems like #8696 was intended to address this, but it's not clear that it does.

The workspace is structured with both deno.json and package.json in the root so that both yarn and deno can be executed from the root.

Should the language server configuration support file globbing patterns in a way similar to the language configuration ?
