Add some minor additional options to userPrefs.jsonc

[karchf]

• Thank you for all the work y'all do on the meshtastic firmware. Just got into meshtastic a couple of months ago...and WHEW the changes are awesome.
• First time contributing here, so apologies for me missing any obvious steps. I'll be posting in the discord shortly to ask for any feedback.
• Added some options around GPS enablement and interval configuration to the userPrefs.jsonc
• Also moved the timezone placeholder that maintained json validity for the file in absentia of other options to the end, so that editors of the userPrefs.jsonc file won't have to remember to add a comma to the tz field and remove one from a later field. Hopefully that saves some attempted build times.

Hey! Thanks for taking the time to make your first patch :)

[karchf]

@fifieldt Thanks for the kind words! Any guidance on the "Merging is blocked" error? I don't think I have a merge commit, anything I need to do to resolve?

When I switch to classic merge experience, it goes away, so I don't really know if its an error.

@karchf , you're likely just seeing those errors as you don't have merge rights to this repository. I do, so I can push the button. However, we normally leave these PRs open for a day or so so reviewers in different timezones can take a look. The Americans should be with us soon :)
