Add vignettes on decorators

[m7pr]

Part of insightsengineering/teal#1475

Adds some explanation about decorators functionality of tmg, since we will remove/reduce confusing decorators vignette in teal. Heavily based on Customizing Module Output vignette currently existing in teal, with adjustments to show teal.modules.general modules.

I provided some comments and suggestions on the vignette. It is very easy to follow.

One technical note is to split long lines by each sentence instead of in the middle of one. This makes it nicer diff if only one sentences is modified and also shows which sentences are more complex.
