Create captain-definition for caprover/one-click-apps

[alyssadev]

I have tested this deploying from https://git.aly.pet/aly/caprover-apps to https://caprover-apps.aly.pet/. I plan to add an index page to this third party repo, or add a markdown renderer for README.md, but that's out of scope for this particular pull request and could be added to this repository at a later date. My hope is to make it easier for other users to create third party repositories for CapRover hosted on their own infrastructure.

☑️ Self Check before Merge

• [x] I will take responsibility addressing any issues that arise as a result of this PR (maintaining this file).
• I have tested the template using the method described in README.md thoroughly
• I have ensured that I put as much default values as possible (except passwords) to ensure minimum effort required for end users to get started.
• I have ensured that I am not using the "latest" tag as this tag is dynamically changing and might break the one-click app. Use a fixed version.
• I have made sure that instructions.start and instructions.end are clear and self-explanatory.
• Icon is added as a png file to the logos directory.
• I've executed the checks if necessary by running npm ci && npm run validate_apps && npm run formatter (If failling run the prettier: npm run formatter-write)

@alyssadev Can you add more details how this works?

[alyssadev]

It compiles the static site for caprover's one-click-apps repo on each push and serves it with nginx

edit: sorry, that wasn't what you were looking for. A block in README.md perhaps?

Would be usefully to have a readme with all steps or maybe a video?
