Autoinstall - a very simple and important feature #817

Hi, thanks for extension.
(i am not well-versed in VSCode extensions, otherwise i would have made a PR instead of issue)
There is a very simple and important thing you can do - in readme you describe the whole process of installing xdebug manually. it's 2022 and we are still doing manual actions to download/install/etc, so, if you can, please take a step forward and do this if you can:

1. check php PATH environment variable to determine the php path
2. run phpinfo() in the background
3. send output to https://xdebug.org/wizard
4. download the suggested file and move to the needed location, rename file
5. update php.ini as written there (if it needs to be updated at all).

That will do the job. which 7million ppl seems to be doing manually.
thanks.
