Remove unused errors.html

Also removed errorModalDetails and displayErrorModal from
dataService since they are no longer used.

errors.html was only active when displayErrorModal was true.
displayErrorModal was only true when activateErrorModal was
called.

activateErrorModal was removed in a previous
commit. activateErrorModal's only use was removed here:
https://github.com/openbmc/phosphor-webui/commit/a38a287ccaa97eddc9df7333e33357b14772d4c6#diff-65affd2488457363c5b9e9266258c3b8

Tested: Searched the repo. Built an image and loaded onto a
        Witherspoon. No regressions observed.
