Bug description

The 2 recent beta releases for 0.16.0 reference the tailscale ACL documentation here, however headscale doesn't support the autogroup:members and autogroup:self functionality referenced there. I would guess it additionally doesn't support the autogroup:internet or autogroup:shared functionality, but I havent tested those

To Reproduce

Attempt to use similar rules to those in the example policy file in the tailscale's ACL documentation or use the recommended initial ACL from tailscale's ACL samples
Observe that headscale constantly logs:
WRN No IPs found with the alias autogroup:members
WRN No IPs found with the alias autogroup:self
And also that with the recommended initial ACL, no devices can see or access each other

Context info

• headscale 0.16.0-beta4
• tailscale 1.26.0 (but not relevant)
