runtime(vim): Update base-syntax, disallow '.' at start of menu item names (#14232)

Disallow '.' at the start of a menu item name.

This is the menu path separator character and should be escaped with a
'\' in this case.

Partially fixes #14230.  "popup" is still incorrectly matched as the Ex
command.
