Add some missing translatable strings

[pvagner]

Came accross a few missing translatable strings.

[t3chguy]

"Addresses" is not an i18n'd string in at least en_EN.json

[pvagner]

Oh yeah, so it should also be added to english? I'm sorry I assumed this will be generated automagically.

[t3chguy]

I think there's a script to run, which will generate it automatically, but its a development task

Hmm, looks like this conflicts with my earlier changes to PowerSelector.

@pvagner if you feel like fixing the conflicts, that'd be great, although I suspect I may have fixed element-hq/element-web#5547 inadvertently, so it might be worth checking if that's still an issue on /develop.

I also broke it by removing _tJsx() :-(

You can use _t() instead now. Let me know if you need help with making the changes.

[pvagner]

@lukebarnard1 My change related to the PowerSelector is no longer needed as you have already addressed that.
I have to revert it and add some more unlabeled stuff e.g. not translatable alt texts on the homepage.

@pvagner let me know when you need me to take another look at this.

[pvagner]

@lukebarnard1: Well, I think this is done. I consider this as a minor thing. The only thing I don't know how to handle is to satisfy @t3chguy's review request.
Everything is committed and merge conflicts are solved.
If I were you I would just accept the PR. But still if you find something you think I might have overlooked, then I'm happy to correct it right away.

Okay, I shall merge because LGTM. Thanks!
