js-mode default binding for js-find-symbol

[Matthias Meulien]

Would it be ok to remove the default binding of `js-find-symbol` in 
js.el?

Current binding (M-.) hides the default binding for 
`xref-find-definition`.

Since packages like eglot or lsp-mode provide the necessary backend for 
xref to do the right job, I found it confusing to have to reenable the 
default global keybinding for buffers visiting files in js-mode...
