Pagination on releases page (#2035)

* Added count to GetReleasesByRepoID so pagination will work

* Separated it out to a new function, can then also leave the API part unaffected

* Remove extra whitespace added in untouched function

* Added comment and corrected name in error handler

* Account for if the user is owner or not in the count

* Also check if repo is draft

* revert back to the correct count in the ReleasesToDisplay loop

* Fixed lint error regarding else with return statement

* Use Cond struct instead of string, corrected name in error handler

* Removed unused return variable names
