RFC Proposal Template enhancement suggestion

As use of the RFC Process grows and proposals to enhance and expand language features increases, I feel there is a need to make a minor amendment to the RFC Template to encourage RFC authors to think about the wider items outside of the RFC proposal including what others can focus on post RFC implementation that will help drive the successful education, use and adoption of these new features.

Therefore I propose that we make an amendment to the RFC template to include an additional small section where the author can outline what they think will aid the successful adoption of these new features within a newer version of the language (v7 / v8 / v9 etc) so that for those, like myself, that blog/present/stream etc can look for suggestions in areas which they can focus on for creating new content that can aid the adoption of these features. This would also help in identifying areas in the supporting tooling, for example PSScriptAnalyzer/PES, to potentially add new features that further help aid adoption. going forward.

I would also suggest to add an additional area where the RFC Author could showcase that with some support & guidance they would intent to implement as well as a section to detail any support they may require to help them be able to implement this.

This could look like the below

Repérez le modèle RFC existant dans le dépôt PowerShell-RFC et comparez-le à la structure Markdown proposée dans l’issue. Ajoutez les sections convenues sur l’adoption et le support de l’implémentation, puis vérifiez que le modèle est rendu correctement et conserve ses métadonnées et ses consignes existantes.
