Move to pypdf

[MartinThoma]

For first-time users, it's confusing that there is pyPdf, PyPDF2, PyPDF3, and PyPDF4. Also non-frequent users get confused about the capitalization of PyPDF2. On StackOverflow, people regularly ask questions about pypdf which are actually about PyPDF2.

Hence we should move "back" to pypdf (all lowercase, no dashes/underscores).

Transition

I will make one last release (+ potentially bugfix-releases) for PyPDF2. That will then be identical (except for the package name) to the same version of pypdf.

So PyPDF2==3.0.0 would be almost equal to pypdf==4.0.0, so that people just need re-name the package they import from PyPDF2 to pypdf + change the package they install.

TODO

• Rename GitHub repository from PyPDF2 to pypdf
• Rename Package inside this repo pypdf
• Try to get the pypdf github organization: https://github.com/orgs/community/discussions/41360 - might be impossible, though https://github.com/orgs/community/discussions/23468

There is a conda forge package for PyPDF2: https://anaconda.org/conda-forge/pypdf2

We should make one for pypdf as well

Looking at the PyPDF2 pypa page, it doesn't look like the notice at the top of the README about moving to pypdf got published there. May be worth making a 3.0.1 release with that info, and also perhaps a deprecation notice in the __init__.py itself for those that just blindly install the dependency without going to pypa?

@MasterOdin Good point! Like that: #1517 ?

I noticed that there's some inconsistent doc links that may relate to this switch:

• the README (etc.) links to https://pypdf.readthedocs.io/en/stable/
• Github's sidebar links to https://pypdf2.readthedocs.io/en/latest/ (note: extra 2)

Fixed! Thank you @huonw

Hey @MartinThoma -- did you try contacting github support? They should be pretty responsive on this I believe! Unless the pypdf org has private repositories they should be able to transfer

[MartinThoma]

I've contacted them, but they said there is nothing they can do
