cp2k-input-tools 0.8.3 Release

[PythonFZ]

Hey and first of all, thanks for this great tool!
We use it to make CP2k compatible with https://dvc.org/ for our research data management and parameter tracking.

We include cp2k-input-tools as a dependency in our package https://github.com/zincware/IPSuite which allows us to build the workflows and much more.

I've seen that you migrated to pydantic v2 in 3706fae .
We have also updated some of our tools to use the new pydantic release.

I was wondering what criteria you have on your side until you release the next version of cp2k-input-tools?
This would allow us, to also release a new version of our tool including cp2k-input-tools` on PyPi, because the package can't depend on the src.

Originally I wanted to resolve #34 and #43 (and with that #69) prior to the release, together with some testing of the aiida plugins depending on this package.
On the other hand there is already enough change in this it seems, hence I did a v0.9.0 release now.
Thanks a lot for letting me know that the package is useful!
