build for 2.13.0-M5

[larsrh]

• simplify build (depend on cats-testkit directly, simplify dependencies)
• drop 2.10.x build (dropped by cats)
• bump dependencies

MiMa fails the check against 0.6.0, but succeeds against 1.0.0. So, if nobody complains, I'd call the next release with this PR merged 1.0.1.

my understanding was that this entire project was going to be moved into a new cats-algebra subpackage

[larsrh]

Apparently that's typelevel/cats#2041. Still, I'd like to get a 2.13.0-M5 compatible release out. Who knows when the merge is going to happen.

[erikerlandson]

I tried this via #221, but either way, could also make use of a 2.13 build

[larsrh]

I didn't see that PR, unfortunately ☹️

[erikerlandson]

this appears to not change any signatures. if that is preferable and gets it merged, so much the better
