fix: respect geo-location settings when creating notes from templates

[sh1vam31]

Fixes #118

Notes created using templates did not include geo-location information (latitude, longitude, altitude), even when the "Save geo-location with notes" setting was enabled in Joplin preferences.

Fix

Added a new utility src/utils/geolocation.ts that:

1. Reads Joplin's note.saveGeolocation global setting
2. Fetches current GPS coordinates via navigator.geolocation
3. Returns null gracefully if the setting is disabled or permission is denied

Updated src/actions.ts to attach latitude, longitude, and altitude
to the note payload when geo-location is enabled.

Testing

• Enabled "Save geo-location with notes" in Joplin Preferences → Note
• Created a note from template via Tools → Templates → Create note from template
• Verified via Joplin REST API that the note has real GPS coordinates:

this logic needs to exactly match what the main joplin app uses to figure out geolocation. this can quickly get out of sync.

I think the alternative should be either of

• making joplin expose the geolocation via a plugin API
• some changes to joplin's note creation api to automatically save geolocation if user has that setting enabled.

@nishantwrp, Thanks for the feedback! I understand the fix needs to happen in Joplin core. Would it be okay if I open an issue in the main Joplin repo requesting either a geolocation plugin API or auto-save in the note creation API?

@sh1vam31 before opening the issue, i'd request you to explore joplin-core a bit to come up with some potential approaches.
