fix(location): use IANA standard for timezone

[matthewmayer]

fix #734

I generated this using a library which already parses the official tzdb data and therefore contains all valid tz names.

npm i @vvo/tzdb

const {timeZonesNames} = require("@vvo/tzdb")
console.log(JSON.stringify(timeZonesNames, null, 2))

I also deleted the list from other locales except en since these were just duplicates of the global list (in theory
another locale might want to have its own list, e.g. en_AU could return only Australian timestamps?)

For now this is okay, but in #735 we need to move it out of en into a global thingy

I was questioning if I should mark that in this PR. @matthewmayer do you want to do that as well? Otherwise I could do that, should be easy enough.

[matthewmayer]

maybe locales might want to override this in future? Like en_AU could return only Australian timezones
