gh-107024 Added copy button to code snippets in documentation

[churnikov]

I added sphinx-copybutton to documentation dependencies, which results in the following button in code snippets

If this is a right thing to do, then this requires a bit more work, as this right now copies the whole code block, but it could be changed through configuration.
It also overrides >>> toggle button where applicable. This has to be fixed or decided to be dropped and made so that copy button copies code without >>> and output.

• Issue: Proposal to add copy button to code examples #107024

We could add this to python-docs-theme instead, to have all users of that theme benefit from this change? That would also enable making the necessary styling changes in one place.

We've been cautious about including third-party extensions, in case downstream redistributors haven't installed them. See the try/except block just below for sphinxext.opengraph.

All the others here are Sphinx builtin extensions, or our own custom ones.

Why the upper version limit?

Sure, I could do that if think that would be better
