Fix mypy error in py3.12

Description

What is this PR

• Bug fix
• Addition of a new feature
• Other

Why is this PR needed?

mypy was complaining on CI, see this failure.

This started happening after neuroinformatics-unit/actions#71 was merged and a new NIU actions release was made. Basically, mypy now runs on Python 3.12 instead of 3.10, so it sees some additional errors (in our case, just 1 error). I was able to reproduce the error in a Python 3.12 environment locally.

What does this PR do?

It fixed the issue mypy was complaining about, by ensuring that time_coords doesn't undergo a type change.
