Feature: Add install from pull request instructions

[glensc]

See pypa/pipx#812 (comment)

Usage:

Install code from Pull request

Replace 838 with a pull request you intend to install

$ pipx install --suffix=@838 'git+https://github.com/Taxel/PlexTraktSync@refs/pull/838/head'
  installed package PlexTraktSync 0.18.0.dev0 (PlexTraktSync@838), installed using Python 3.10.2
  These apps are now globally available
    - plextraktsync@838
done! ✨ 🌟 ✨

You can also use a convenience wrapper (this requires you install plextraktsync with pipx first):

$ plextraktsync self-update --pr 838

@tony saw your comment. can you help out?

This project isn't installable even when using an existing tag or branch:

$ pipx install --suffix=@pr git+https://github.com/Taxel/PlexTraktSync@0.18.21

what could be missing/wrong? and how to solve?

[glensc]

Removed temporarily the -i: ca31725. removing it will likely break dependabot, so it can be only temporary.

but now next problem:

➜ pipx install --suffix=@pr 'git+https://github.com/Taxel/PlexTraktSync@pipx-installab
le'
  WARNING: Built wheel for PlexTraktSync is invalid: Metadata 1.2 mandates PEP 440 version, but '0.18.x' is not

Ok, now can install from branch:

If you got it working that's excellent @glensc. That was the first time I've customized the command

[simonc56]

Can this PR be merged ?

What does it mean :

projects need to be installable from git branch

[glensc]

it's not complete, currently contains a hack that should not be merged:

• ca31725

for it, a fix is proposed, but not merged:

• Fix: Skip lines with -i s0undt3ch/setuptools-declarative-requirements#7

[glensc]
