[Tracking] Scheduled CI is failing on main

[norlandrhagen]

It seems like the scheduled CI on main started failing around Oct 2nd. Opening this issue to track it.

Seems to be mypy / type hinting related:

Run mypy virtualizarr
virtualizarr/manifests/manifest.py:137: error: Incompatible types in assignment (expression has type "ndarray[Any, dtype[Any]]", variable has type "ndarray[Any, StringDType]")  [assignment]
virtualizarr/manifests/manifest.py:144: error: Type argument "StringDType" of "dtype" must be a subtype of "generic"  [type-var]
virtualizarr/manifests/manifest.py:144: note: Error code "type-var" not covered by "type: ignore" comment
virtualizarr/manifests/manifest.py:199: error: Incompatible types in assignment (expression has type "ndarray[Any, dtype[StringDType]]", variable has type "ndarray[Any, StringDType]")  [assignment]
Found 3 errors in 1 file (checked 37 source files)
