Improve Copy for "Urbit Link Handling" Landscape preference

[urcades]

Describe the bug

Currently, the interface shown above is written in such a manner that it's hard to tell what it's enabling, or what it's actually doing for the person considering toggling it.

I'd like to propose a simple change to the wording here, to make it completely clear what's going on:

Current Copy:

Handle Urbit links:
[ ] Automatically open urbit links when using this browser.

Proposed Copy:

Enable Urbit links in this browser:
[ ] Allow Urbit-native links (such as links to groups or apps) to be clicked and navigated to within this browser. This option will need to be set for each browser you access your urbit with.

Tagging @e-shee in here to get an eye on the above suggestion - if need be, we can walk through what exactly this things does, and whether the suggestion above is actually an improvement.

[e-shee]

I suggest something like:

Open Urbit links in this browser:
[ ] Enabling this makes Urbit-native links clickable and navigable within this browser.

@e-shee so much better, thanks a bunch for giving this a look!
