Add new deploy app command

[nenb]

This PR adds a new command: deploy-app.

deploy-app

• Opens the URL for the create-app page in a new browser tab. Also passes a query parameter for filepath that is generated from the current workspace in JLab. Accepts an argument origin ('menu', 'context-menu' etc) that allows controlling what icon is displayed.

Documentation

Access-centered content checklist

Text styling

• The content is written with plain language (where relevant).
• If there are headers, they use the proper header tags (with only one level-one header: H1 or # in markdown).
• All links describe where they link to (for example, check the Nebari website).
• This content adheres to the Nebari style guides.

Non-text content

• All content is represented as text (for example, images need alt text, and videos need captions or descriptive transcripts).
• If there are emojis, there are not more than three in a row.
• Don't use flashing GIFs or videos.
• If the content were to be read as plain text, it still makes sense, and no information is missing.

Thank you, amazing! You should be able to manually update the snapshots by downloading the files from https://github.com/nebari-dev/jupyterlab-jhub-apps/actions/runs/11022641935?pr=1

Let's see if bot works here:

Hmm, this did not work. Maybe needs a timeout?

Looking at the darwin snapshot:

• the kernel busy indicator (the black circle) will flip on and off depending on the kernel state; we may want to ensure that kernel is in idle state (have a look at the tests in JupyterLab to see how to do that)
• the deploy icon looks great here; I think the mockups also included a "Deploy App" label when displayed in the toolbar, do you want to include it straight away or in a follow-up PR?

[nenb]

I will add the "Deploy App" label in the toolbar in a follow-up PR, just to try and get this PR merged.

Updating snapshots failed because of timeouts I think:
