Copy options install options for latest, and requirements file

[vincentdavis]

What's the problem this feature will solve?
My normal workflow when starting or working on a project is to:

1. Find a package I need on pipy.
2. Look at the release history.
3. Choose the newest
   Problem steps
4. Click the copy install text that is formatted pip install Django==4.2.4
5. Paste this into my requirements file
6. Delete the 'pip install `
7. Then my IDE makes it easy to install this package.

Describe the solution you'd like
I am open to suggestions but my goal with be to be able to quickly:

• An option to click copy and get only Django==4.2.4 where 4.2.4 is the newest version
  Maybe this could be done by adding one additional copy icon.
  A bit more complex with be:
• add a copy newest icon for the current that would copy to the clipboard pip install Django==4.2.4
• Add a third icon for coping only Django==4.2.4

This is probably something I can implement and make a pull request, I would be open to suggestions.

This would be another context where a standard tool/entrypoint for modifying PEP 621 metadata would come in handy, since PyPI could offer a single copy-paste selection for some-tool add Django==4.2.4.
