List Imba starters for different server hosts (Netlify, GitHub Pages, etc)

[codeluggage]

After https://github.com/imba/imba/pull/703 was merged, we added new starter templates in https://github.com/imba/imba/pull/707.

We have a few examples + guides for deploying to different server providers / static site hosts now:

• https://github.com/codeluggage/imba-on-github-pages
• https://github.com/codeluggage/imba-on-netlify

These are being added to the template in https://github.com/imba/imba-vite-template/pull/7 - but it would be great to look these up from within imba.io as well.

Next steps

• [ ] Add an overview of starter template usage, with enough keywords that it becomes easy to find with the Imba.io lookup
• [ ] Check with community if there are any other uses of the templates, and include them
