Closes #35930

When a TypeScript file is renamed or moved, vtsls can automatically
update the imports in other files. It pops up a message with the option
to always automatically update imports. This choice would previously
only be remembered for the current session and would pop up again after
a restart.

Now we persist that choice to the vtsls LSP settings in Zed, so that it
remembers across editor sessions.

Release Notes:

- When renaming a TypeScript or JavaScript file, the selected option to
automatically update imports will now be remembered across editor
sessions.
