Bump tailscale dependency

[RyanDraves]

I saw a security patch notice on my tailscale dashboard while tinkering on my setec deployment, so I bumped the tailscale dependency to the latest release and confirmed that works fine.

Additional discussion: this patch originally added support for configuring what tags to advertise, which is now supported in the updated library. However, I kept getting errors from the node registration about the authkey not being allowed to do that, even if I select the same set of tags when creating the authkey. I'm not sure what the intended workflow for this is, but the correct tags do get advertised if I select them when creating the authkey and don't configure them when creating the tsnet.Server. :shrug:
