Improve update-locales script and fix locale processing bug (#23240)
The locales of Gitea has been broken for long time, till now, it's still
not fully fixed.

One of the root problems is that the `ini` library is quite quirky and
the `update-locales` script doesn't work well for all cases.


This PR fixes the `update-locales` script to make it satisfy `ini`
library and the crowdin.

See the comments for more details.

The `locale_zh-CN.ini` is an example, it comes from crowdin and is
processed by the new `update-locales.sh`. Especially see the `feed_of`:

# the "ini" library for locale has many quirks
# * `a="xx"` gets `xx` (no quote)
# * `a=x\"y` gets `x\"y` (no unescaping)
# * `a="x\"y"` gets `"x\"y"` (no unescaping, the quotes are still there)
# * `a='x\"y'` gets `x\"y` (no unescaping, no quote)
# * `a="foo` gets `"foo` (although the quote is not closed)
# * 'a=`foo`' works like single-quote
# crowdin needs the strings to be quoted correctly and doesn't like incomplete quotes
# crowdin always outputs quoted strings if there are quotes in the strings.
# this script helps to unquote the crowdin outputs for the quirky ini library
# * find all `key="...\"..."` lines
# * remove the leading quote
# * remove the trailing quote
# * unescape the quotes
# * eg: key="...\"..." => key=..."...
