Add credo-language-server support

[wkirschbaum]

This is a linting server for the Elixir programming language.

• clients/lsp-credo.el: New file.
• docs/lsp-clients.json: Add credo-ls entry.
• lsp-mode.el: Add directory for server cache.
• CHANGELOG.org: Add entry.

This is exclusively for elixir-mode, elixir-ts-mode and heex-ts-mode ( The Elixir langauges ). Does it make sense as a separate file? Feels cleaner.

I dont see a setup for automatic installation?

[wkirschbaum]

@yyoncho i am a bit unsure on how this works. its a repo download and unzip... let me try to add it now.

[wkirschbaum]

@yyoncho latest changes has the setup for automatic installation. Pretty neat feature :).

Will it be easier for you if i make sure the bin/credo-language-server script is always uploaded as an asset on the github release?

[wkirschbaum]

Thanks, i updated the PR to use the new release file structure.
