[web][website-redesign] Fix horizontal line around the "OR" text that is not vertically aligned (#17913)

* Fix horizontal line around the "OR" text is not vertically aligned

* Change "or" text to be capital

new login and register have their "or" text capitalized, so it would make sense to make homepage have the same capitalization rule too
