fix: environment name should be pypi

[lwasser]

Addresses #17374

This pr updates the screenshots for trusted publisher to ensure the environment name is listed as pypi rather than release.

Dev instructions were tricky to follow

Friends, I wasn't able to get docker to run as expected. I first went down a rabbit hole that I realized was building the entire warehouse. I did this because the README suggested that I follow the detailed instructions, but i think that I should have only followed the

• git/clone part
• docker compose setup part (i already have docker installed but not all users will)

I wonder if it's worth adding a note in the dev docs that says - if you want to only build the docs - go to (and add links to the readme for the user docs). I'm still wrapping my head around your setup, so this could also be my misunderstanding.

Let me know, however, if this PR seems ok. It's just image updates so in theory i shouldn't need to rebuild the docs locally (but i do want to figure out how to).

There's a subtle difference with this one: the "Environment name" field is focused and so it has a blue outline.

Also, for consistency's sake, these screenshots were previously made by taking a "node screenshot" of the enclosed section:

Doing this is not strictly necessary but will keep the cropping around the element the same as before.
