Inlay hints depend on LSP server settings, but servers do not update the
initialization options and query hints with old settings.

Generally, we cannot know whether a certain option can be changed
without server restart, which the name of the options implies too, so be
on the safe side and restart the server.
Hints will update automatically after the server either sends a /refresh
request or reports its work progress end after startup.

Release Notes:

- Fixed LSP server not restarting after `initialization_options`
settings changes
