i18n(en): new repo form: remove full stops from placeholders, clarify labels (#4709)
Just a small PR fixing some lines.
* removed full stop from placeholders, they were placed inconsistent and it doesn't really makes sense to have them in placeholders. It's usually either no full stop or ellipsis.
* s/Issue labels/Labels - obviously labels aren't used just for issues
That's about it. I may or may not send other improvements for this page later, this is just a simple PR that doesn't need testing.
