Something is wrong in CI

[maximilianruesch]

The CI failure seems to be unrelated to guppylang. Local debugging revealed Quantinuum/tket#2185

[aborgna-q]

tket requires pytket >= 2.1.0. This was a base dependency before, but is now in the tket[pytket] extra. I wonder if we should bump the minimal pytket version here too.

Anyways, LGTM

[maximilianruesch]

tket requires pytket >= 2.1.0.

But only as optional, and (according to a comment in tket) only for type-checking. Nvm, you mentioned that.

We can bump the pytket version for test purposes here as well, and should then probably bump the version in the optional extras for guppylang and guppylang-internals as well.
