Support internet bridging

(Copied from https://github.com/wpilibsuite/allwpilib/issues/7928, as this repo seems more applicable)

Is your feature request related to a problem? Please describe.
When you have the computer connected to the robot to code, not having an internet connection is a massive pain. Also, if teams are using onbot, having the ability to pull from and push to GitHub and such is a huge benefit.

Describe the solution you'd like
Provide a nice UI for enabling bridging, so when you are connected to the robot, you also have internet connectivity. The RPi hardware supports this (https://raspberrypi.stackexchange.com/a/89804), so it should theoretically just be a matter of having an easy way for teams to enable this.

Here's what it might look like:

                 wifi                         wifi uplink         wan
 ds-&-laptop <~.~.~.~.~> (ap@wlan0)RPi(wlan0) <.~.~.~.~.> router <───> INTERNET
            ╲             ╱               ╲
           (dhcp    192.168.43.1         (dhcp
         from RPi)                    from router)

Describe alternatives you've considered
A second USB WiFI adapter plugged into your computer, but that's extra hardware that is not needed, and also Macs don't really support that setup.

Additional context
Was a Discord convo, putting the information I found here so it doesn't get lost/forgotten.

No files, tests, or entry points are identified. Start by evaluating the linked Raspberry Pi networking approach and defining how the UI should enable bridging between the robot access point and the Wi-Fi uplink; done means a connected computer can reach the internet through the robot.
