refactor(item): remove no-lines attribute in favor of lines property (#14407)

* docs(components): update grammar and docs

* docs(item): update item documentation and add usage

* test(item): add lines test

* feat(list): add lines property to override borders on items

* feat(item): add lines property to override borders on items

* refactor(item): remove old uses of no-lines attribute

* fix(item-sliding): update item options to show border

- show the border on left options only if in a full list
- show the border on both options only if in an inset list (or ios by
default)
- don’t show border on either for no lines list (and md by default)

also renames isRightSide to isEndSide to match the side values

* chore(package): update package lock

* style(item): fix lint errors

* test(item): update item tests

* refactor(item): remove the custom styling of last child items

instead of us overriding first/last child items to have borders we are
going to add to the documentation how to style items with a full border

* fix(item): apply border to item inputs for MD mode

* docs(components): update docs based on new build

* docs(usage): update item usage to show lines being used

* fix(item): do not set the padding right to 0 on an item by default

* fix(item): cast lines to boolean
