Adjust patch release template file names
What does this MR do and why?
With the new patch release process, we can remove the now unused patch.md.erb
template and rename the newer templates to make a bit more sense.
In this MR we:
- Remove unused
templates/patch.md.erb
- Rename
templates/patch_multi_version.md.erb
totemplates/patch.md.erb
- Rename
templates/patch_release_multi_version_blog_post_template.html.md.erb
totemplates/patch_release_blog_post_template.html.md.erb
