Issue #5996 - Fix Android Studio warnings in LocationPickerActivity.kt

[savsch]

Description (required)

This fixes Android Studio warnings in app/src/main/java/fr/free/nrw/commons/LocationPicker/LocationPickerActivity.kt, as described in #5996

---

Note that just one weak warning remains:

Package name 'fr.free.nrw.commons.LocationPicker' part should not start with an uppercase letter

I didn't try to fix this because I believe that renaming the package falls outside of the scope of this issue (#5996). I request the reviewer to clarify whether this is the case or not.

Edit: fixed. No warning or weak warning remains.

---

The changes made include:

• Replacing deprecated Html.fromHtml(String) call with HtmlCompat.fromHtml(String, HtmlCompat.FROM_HTML_MODE_LEGACY)
• Replacing deprecated getParcelableExtra method calls (for Intent and Bundle) with corresponding calls in IntentCompat and BundleCompat.
• Replacing deprecated getZoomLevel call with getZoomLevelDouble (for org.osmdroid.views.MapView)
• Reformatting lines longer than 100 characters so as to comply with the code style.
• Renamed fr.free.nrw.commons.LocationPicker to fr.free.nrw.commons.locationpicker.

Tests performed (required)

Tested BetaDebug on Medium Phone (AVD) with API level 34 and on a physical device with API Level 33. Also made sure LocationPickerActivityUnitTests pass.
