[installer]: add example for post-processing the YAML

Documentation

[csweichel]

Are we sure we want to point this out? If so, we should make it drastically clear that by going down this path there will be no support available.

@csweichel we have to put something* as there are lots of people in Discord etc saying "I can't do x in the Installer that I could do in Helm and need it for ". For the most part, these are things that we're unlikely to want to add in and certainly not in the short term. By adding an example of what I mean by "you can post-process the YAML", that should reduce the support requests we need to detail

* This is my opinion on "something". I'm happy to debate if it's the correct something

[mrsimonemms]

@csweichel I added a "here be dragons" warning to the readme

That makes sense. It also means that for future interactions we need to ask if folks "customised" their rendered YAML.

With the added warning, I think it's fine to have it in the readme file for now.
