Improve the networking disabled error message

[ironnysh]

Hi,

When users try to install a theme or a plugin in a Playground instance whose networking feature is disabled (the default state), they get an error message, which could be more helpful.

While the discussion in the GitHub issue is valuable, it doesn't provide a practical solution to the problem (namely, enabling networking 😀).

I'd suggest the following rewrite of the text here:

Note

Network access is an experimental opt-in feature, which means you need to enable it to allow Playground to access the Plugins/Themes directories.
You can enable global networking support using the Query API (for example, https://playground.wordpress.net/?networking=yes) or the Blueprint API (add "features": { "networking": true } to the JSON file).

Bonus: A unified error message for both the Themes and Plugins pages.

I'm happy to open a PR if the proposed changes are good to go.

A few additional comments:

• There's no reference to the networking option in the Blueprints API documentation—only in the Blueprint JSON schema.
• Should streamline the boolean value: yes in the Query API vs. "true" in the Blueprints API.
• The error message includes a Try Again button, which does nothing.
• The error message appears twice on the Featured plugins tab.

This sounds fantastic @ironnysh! If you'd like to open a PR, I'll be happy to review and merge :)

That's a good note, we could make the Query API accept both yes and true, and perhaps even use true in the documentation.

Coolio, on it. Thanks!

I imagine most developers would associate boolean with true, but doesn't hurt to have options ;-)

BTW, I found a reference to networking in the documentation. I'll open a PR for this one as well to clarify common use cases covered by networking (there's also this issue).

Finally, can (or even should... 🤨) the Try Again button be used to regenerate the same Playground instance with networking enabled, or is it too much? :-)

Hmm, the button is part of core. Is there a way to hide it?
