Share Plugin: improvements for Android 11
- Do not ask for WRITE_EXTERNAL_STORAGE in Android 11+ (writing to "Downloads" is allowed by default since 11).
- Do not check for permissions before receiving a file. Try and let it error out, instead of silently doing nothing.
- Fix not offering to open content:// urls (we checked the URLs to be file:// urls to then convert them to content://).
- Better permission explanation text.
