Wrapping strings in double quotes such as

<string name="my_string">"\n    This is my string.\nHello"</string>

Will import the string in glotpress as "\n This is my string.\nHello" instead of \n This is my string.\nHello.
In order not to update glotpress and translate.wordpress.org which would be costly, let's revert to using simple escaping of xml entities and not use "". In theory we should only lose the ability to have leading and trailing whitespace characters in a string, which is not something that happens frequently. So the resulting sting in glotpress will be This is my string.\nHello.

To make sure the created xml is valid we run xmllint automatically once the npm script is complete.

To test:

• Check that XML looks valid in bundle/android/strings.xml
• Optional: copy-paste all the strings from bundle/android/strings.xml into WordPress/src/main/res/values/strings.xml in WPAndroid and build and run the app with those strings. You can boot the block editor in debug mode to see translations being printed in the console
• Optional: Try to edit gutenberg-android.pot, adding special characters to it such as <, >, ", \n..., then run ./bin/po2android.js gutenberg-android.pot bundle/android/strings.xml, it should create a valid xml file. Validate file with yarn genstrings:android:check
