topology2: intel: bt-generic.conf: fix rate constraints

Commit c77a4fe ("topology2: pcm_caps: Remove defaults for
rate_min/rate_max") changed how rate constraints are described in
topology. After this change, the rate_min/max was ignored by SOF Linux
driver and the rate was incorrectly limited to 48000Hz for these
topologies.

Fix this issue by enumerating the supported sampling rates with "rates".
