Bugfix/#5816 - Fixed i18n key in register page for "haveAccount"

[BlackBearFTW]

What is the current behavior?

It simply doesn't work since the wrong i18n key is specified pages.login.buttons.haveAccount but the i18n translation files do not have that key and it should instead be pages.register.buttons.haveAccount

What is the new behavior?

UI libraries and core now uses pages.register.buttons.haveAccount in auth/register page
