Minor cleanup to new textdocument/formatting feature

* README.md (Language feature): Tick textDocument/formatting

* eglot.el (eglot-client-capabilities): Add formatting capability.
Also move codeAction capability to the correct section.

(eglot-format-buffer): Remove unused lexical variable before-point.
