In some screenshots it seems like there wasn't really previously any different styles for some link states
the changes to hmrcAccountMenu were planned, see jira ticket PLATUI-1646 for context
I've tried not to make other changes to the account menu than what we agreed, there might be, on seeing the screenshots, more changes or adjustments that people want. Happy to do some of those as part of this, but I didn't want to pre-empt any requests so I've somewhat letter-of-the-law'ed my changes (hopefully)
while I was doing this, I noticed the language selector links in header had also got an accessibility problem with their link styles on hover, so I fixed that at the same time
