Social preview image autogerated by github, and social media posts needs to be consistent over pipelines

Description of the bug

GiHub use the release notes to generate the social preview image.

Classic example https://twitter.com/nf_core/status/1760983113294078288 has no pipeline name and the tweet had a bit too much info (twice the version number):

Pipeline release! nf-core/smrnaseq v2.3.0 - v2.3.0 - 2024-02-23 - Gray Zinc Dalmatian!

So I'd say we need also to fix the announcement GHA, so that the version is displayed just one.

Plus provide guidelines or template for release notes, and release name because none are consistent:

examples:

I do love molkart that specified the pipeline name in the release note
