Support for URL of renarde application

[angelozerr]

Quarkus renarde application have some custom logic for the compute of URL different from JAX-RS, see https://quarkiverse.github.io/quarkiverse-docs/quarkus-renarde/dev/index.html#_methods

It should be nice to provide an extension point in lsp4mp to support those URLs for:

• codelens
• workspace symbols.

This extension point should be used for the both feature to:

• detect which method is an HTTP methods
• compute the proper URL

Fixed with #796
