Eglot: check correct capability name in eglot-imenu (bug#64682)

* lisp/progmodes/eglot.el (eglot-imenu): Declare the correct name of
the server capability providing textDocument/documentSymbol.

Without this change, eglot-imenu always aborts even when used with
servers supporting textDocument/documentSymbol.
