On current master branch, running M-: (eglot-imenu) in buffers 
using LSP servers supporting the textDocument/documentSymbol 
request always results in an early exit since the server 
capability is NOT named "textDocument/documentSymbol", but rather 
"documentSymbolProvider".

This patch corrects that, so that now (eglot-imenu) works as 
expected.
