fix(localize): improve matching and parsing of XLIFF 1.2 translation files (#35793)
Previously, the `Xliff1TranslationParser` only matched files that had a narrow choice of extensions (e.g. `xlf`) and also relied upon a regular expression match of an optional XML namespace directive. This commit relaxes the requirement on both of these and, instead, relies upon parsing the file into XML and identifying an element of the form `<xliff version="1.2">` which is the minimal requirement for such files. PR Close #35793
