fix(lsp): don't pre-load documents matched in the config file's "exclude" (#19431)

This prevents documents specified in a deno.json's "exclude" from being
pre-loaded by the lsp.

For example, someone may have something like:

```jsonc
// deno.json
{
  "exclude": [
    "dist" // build directory
  ]
}
```
