bug#64859: 30.0.50; Eglot: codeAction.resolveSupport capability is incorrect

[Matan Peled]

I'm using a recent snapshot build.

When trying to use Eglot on Rust code (with the rust-analyzer LSP
server), it crashes complaining about the InitializationOptions message
being misformed.

This is due to this commit:
https://git.savannah.gnu.org/cgit/emacs.git/commit/lisp/progmodes/eglot.el?id=3b7273f4ae3623962c5d5fdc922a62af1136f448

resolveSupport is supposed to be a list, not a boolean, see here:
https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_codeAction

I'm not sure what properties Eglot supports here, so I'm not certain on
what the correction should be.
