chore(ui): Remove the max line width from the YAML formatter

[flippingbits]

By default, js-yaml breaks lines after 80 characters.

I removed the limitation, so we do not break lines after a specific length, which could become problematic when, for instance, breaking inlined Python functions that contain comments into multiple lines.

Example:

I moved the YAML formatting to a central helper function so we do not have to maintain configuration at multiple locations.
