Ability to share logs with standard UIActivityViewController

[mitchins]

Is your feature request related to a problem? Please describe.
Not all test devices have email setup and it would be quicker to drop the file via airdrop to your Mac as well.
Additionally allows sharing via standard workspace tools like Slack or MS Teams.

Describe the solution you'd like
Allow the standard iOS UIActivityViewController to handle sharing of the log files.

Describe alternatives you've considered
It's possible to email it today, but not always available on devices and it can unnecessarily clog up the email inbox.

Additional context
I would be happy to provide a PR, as it could be another button below share logs, e.g. "share logs via ..." - or an action sheet on the existing sharing.
Please let me know your thoughts, I believe it would be a productivity win.
