chore(lsp): check rename capabilities before send rename action

[ttys3]

check rename capabilities before send rename action

and logging a kindly warning message to the log file so that the user knows that it maybe a client config problem.

some lang server implementation (like intelephense) need a license key configured to do rename action.

in neovim, the config looks like:

lsp.intelephense.setup {
	settings = {
		intelephense = {
		        licenceKey = "the-actual-license-key",
		},
	},
}

in helix, one may miss configured like this:

in languages.toml

[[language]]
name = "php"
config = { "intelephense" = { "licenceKey" = "the-actual-license-key" }}

but the correct init config in helix should be like this:

[[language]]
name = "php"
config = { "licenceKey" = "the-actual-license-key" }

with the warning message in the log, people will easy to debug and confirm the config issues.

It would be better to show an editor error with editor.set_error in the calling code if it returns an Err variant from here.

Cool! Also, some language servers don't have rename yet, like the bash one.
