Fix version parsing in setup.py

[vanmatten]

The last character of the version is cut out by [:-1] in Path("moviepy/version.py").read_text().strip().split('"')[1][:-1].
Eg: 2.0.0.dev2 become 2.0.0.dev, which Python build reads as 2.0.0.dev0.

In fact Path("moviepy/version.py").read_text().strip().split('"') gives ['__version__ = ', '2.0.0.dev2', ''] so removing the last character isn't needed.

I'm not sure why this was closed/deleted, I can only see that tests failed (not why), did this not solve the problem after all?

Tests failed as in the main branch when I created the commit and I don't know why.
This commit do exactly what I have written in the title, I closed it because the pull request of v2.0 fix this issue as others.

If you think that reopening this pull request is usefull, i'll do it.
