fix(plugin-stealth): Append patch version to UA hint platform version

[momala454]

https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Sec-CH-UA-Platform-Version Sec-CH-UA-Platform-Version contains dot-separated major, minor and patch version numbers The user agent may not contains 3 numbers, example on windows 10 it contains Windows 10.0, so we add the patch version at the end.

Take note that on linux the version seems to contains the kernel version, which this evasion doesn't get so if you set maskLinux to false on linux, the platformVersion will be empty while it shouldn't.

On android, on my phone on android 11, there is no header Sec-CH-UA-Platform-Version so i don't know if it must be removed

The bitness is also not filled.
