Linus Groh 649d2faeab Everywhere: Use "the SerenityOS developers." in copyright headers
We had some inconsistencies before:

- Sometimes "The", sometimes "the"
- Sometimes trailing ".", sometimes no trailing "."

I picked the most common one (lowecase "the", trailing ".") and applied
it to all copyright headers.

By using the exact same string everywhere we can ensure nothing gets
missed during a global search (and replace), and that these
inconsistencies are not spread any further (as copyright headers are
commonly copied to new files).
