fix invalid escape sequences (python 3.12 SyntaxWarning)

[ehossack]

I don't see any reason to not do this (nothing in sphinx?).

As referenced in #458

[ehossack]

(I could add a changelog section, but not sure what version this would target. 1.30.0? 1.29.1?

This seems like this regexp was invalid from the beginning.

Instead "fix" should be just adding r i.e. r'...' as otherwise this ? will mean d is optional

[ehossack]

good point.

As for the changelog, we use towncrier to manage main file, so you just create a new one and don't worry about versions yourself.
Please instructions in https://github.com/Backblaze/b2-sdk-python/blob/master/CONTRIBUTING.md#changelog .

P.S. thanks for contributing

@ehossack the changelog files need to follow a specific naming scheme. If it's a fix, it should be +<unique-change-name>.fixed.md, e.g. +syntax_warning.fixed.md. Once you rename the file, it should be good to go. :)

Edit: since this fixes issue #458, the name of the changelog file should be 458.fixed.md.

Sorry, new process and also I didn't properly read the section you linked 😅
