fix: artifacts content indentation

[juanmcampos]

This fixes an issue with indentation of the files content.

It works with python, etc

this is an example of how indentation is broken

this is how it gets fixed

hey thanks for this PR.
i am skeptical on manual indentation fix. not a big deal for typescript or javascript but critical for python.

need to test this with python code. does this work if the indentation is already correct?

[juanmcampos]

Hey thank your for the review.

This happens with any generated code not just python.

It should work for any code not just python just mentioned as I read someone had the same problem, what I found out it's related to the artifact indentation.

Code here // <- generated code keeps indentation from the llm

The PR has a fix that takes into account the indentation in general so for code that is not it should work as it leaves the code as is.

As far as Python goes, we do not have support for python anyways no?

sorry miss clicked on close

I tested a small pyhton code and it generates the code and runs basic code, it fails sometimes with non basic stuff but that should be an issue webcontainers so its unrelated.

However this PR is not for python, the issue with indentation can be replicated with any code being html, css, jsx, etc

Notice the first line is trimmed properly but from second line any code gets the indentation from the bolt's arctifact markup

I will test this PR with different model outputs and see if it works for all

I wanted to have a different approach on this. the root cause of llm putting an extra indentation on files was due to system prompt having such indentation in its examples. I have modified the examples best represent the expected outputs
let me know if this fixes the issue #1139
rather than having hardcoded solution its better to encourage the llm to produce correct format
