update to tensorflow 2.8.0

[nschloe]

Your install_requires is taken from requirements.txt where the version number is fixed. This is usually not a good idea because you prevent Python users from updating their installation when guesslang is installed. (Remember Python doesn't install packages locally, per package, but globally.)

A better solution is to provide a version range, usually between major versions, e.g.,

tensorflow >=2, <3

There are quite a few other things that could be improved in an around metadata handling in guesslang.

I just cloned this repo, removed the 2.5.0 requirement from the tensorflow requirement and guesslang installed and seems to operate fine with tensorflow 2.10.0 installed.

+1, this is causing issues with typing-extensions conflicting. Would be awesome to just update this and publish a new package!
