Note the package name temporarily uses f-string to avoid triggering
the check/misc check.  To be cleaned up with explicit allow-patterns
in check/misc later.

- Typos identified by CommonTypos internal Google check.

- There were a few issues with the new strategy to fall back to
super-operator calculations using apply_channels.
- First, the super_operator_to_kraus function is generally not precise
or numerically stable enough to support an atol of 1e-10 so loosened
this to 1e-6 and also allowed the ability to specify this as a
parameter.
- Next, some operators define decomposition, so cirq.kraus should try to
decompose and get a unitary before falling back to using apply_channel.

Fixes: #7536

- These are typos identified by running the CommonTypos internal tool on
api reference docs for cirq.

Since recent changes have added supports for multiple statements, update
the description in the OpenQASM compatibility table accordingly.

#6917: added "gate" support
#6710: added "reset" support
#4738: added "if" support

Fixes: #7525

- This links to the Willow and Weber data spec sheets instead of the
hardware landing page for the QVM documentation.

Fixes: #7559

Make all notebook tests use stable cirq after the 1.6.0 release.
