v134, v133 woes
feature detection

```js
try {if ('lij' == Intl.PluralRules.supportedLocalesOf('lij').join()) {return 134}} catch(e) {} // 1927706
```
It's my version 134 test. They added it wayback in UDK v105 then rolled it back - these changes come with updates to ICU. On windows I correctly only trigger this in v134 or higher. So I wonder if something else is going on in linux. I'm usually loathe to use anything that an extension could tamper with, but this is low risk and I couldn't really find anything else - I need changes that are not pref based. I didn't 100% confirm that [1927706](https://bugzilla.mozilla.org/show_bug.cgi?id=1927706) is the change, but 99% sure it is.
what do you get if you run this in the console
```js
function test() {
let aCodes = [ 'ie', 'lij', 'oc', 'st', 'szl', 'tn', 'za']
let aIntl = ['C', 'DTF','DN','DF','LF','NF','PR','RTF','S']
let oData = [], test = ''
aIntl.forEach(function(method){
try {
if (method == "C") {
test = Intl.Collator.supportedLocalesOf(aCodes)
} else if (method == "DTF") {
test = Intl.DateTimeFormat.supportedLocalesOf(aCodes)
} else if (method == "DN") {
test = Intl.DisplayNames.supportedLocalesOf(aCodes)
} else if (method == "DF") {
test = Intl.DurationFormat.supportedLocalesOf(aCodes)
} else if (method == "LF") {
test = Intl.ListFormat.supportedLocalesOf(aCodes)
} else if (method == "NF") {
test = Intl.NumberFormat.supportedLocalesOf(aCodes)
} else if (method == "PR") {
test = Intl.PluralRules.supportedLocalesOf(aCodes)
} else if (method == "RTF") {
test = Intl.RelativeTimeFormat.supportedLocalesOf(aCodes)
} else if (method == "S") {
test = Intl.Segmenter.supportedLocalesOf(aCodes)
}
} catch(e) {
}
oData.push(method +': ' + test.join(', '))
})
console.log(oData.join('\n'))
}
test()
```
I get this in v134
```
C: lij, st, tn
DTF: ie, lij, oc, st, szl, tn, za
DN: ie, lij, oc, st, szl, tn, za
DF: ie, lij, oc, st, szl, tn, za
LF: ie, lij, oc, st, szl, tn, za
NF: ie, lij, oc, st, szl, tn, za
PR: ie, lij, oc, st, szl, tn, za
RTF: ie, lij, oc, st, szl, tn, za
S: ie, lij, oc, st, szl, tn, za
```
