fix: Launchpad plugin path: keep namespace

[Regloom]

Launchpad plugins path should follow URL approach defined for regular apps as stated in this file below: "cds-plugin-ui5 uses the appid as default route (combination namespace + component)"

@Regloom :
I would suggest to first perform a check to see if cds-plugin-ui5 is loaded before enforcing this convention. (like e.g. https://github.com/geert-janklaps/cds-launchpad-plugin/blob/054ec1bade6d0e91bf8fc8a0ea3c01afcd31205e/src/index.ts#L150C5-L150C80)

This plugin has no hard dependency on cds-plugin-ui5, so we need to make sure that we have backwards compatibility for projects not using cds-plugin-ui5.

I faced the same issue today. TypeScript launchpad plugin fails to load.
JavaScript plugin loads just fine.

My observations are as follows:

1. Original code of cds-launchpad-plugin
   1. JavaScript plugin URL http://localhost:4004/jsplugin/webapp/Component.js - works fine
   2. TypeScript plugin URL http://localhost:4004/tsplugin/webapp/Component.js - does not work
2. Solution proposed in this PR (url: component + "/webapp",)
   1. JavaScript plugin URL http://localhost:4004/com.ns.jsplugin/webapp/Component.js - does not work
   2. TypeScript plugin URL http://localhost:4004/com.ns.tsplugin/webapp/Component.js - does not work
3. My approach to fix it (url: component,)
   1. JavaScript plugin URL http://localhost:4004/com.ns.jsplugin/Component.js - works fine
   2. TypeScript plugin URL http://localhost:4004/com.ns.tsplugin/Component.js - works fine

As this pull request seems pretty much dead and there is no consensus, what the actual fix should be, I suppose I will be better off with my own fork that I will refer to in my project.

@rasmk: do you have a minimal reproducible example I can use to do some analysis?

[rasmk]

@geert-janklaps my project is anything but minimal 🙂

But I removed everything unrelated and only left two launchpad plugins: one implemented in JS and one in TS

You can use this repo to reproduce the problem. See README.md for further details.

I hope this helps.
