7.4 is being used on my system and is recommended by Nextcloud.
So I feel like this may as well be added.

"php_version" to "php_ver" in README

*Fix* Debian does not have a "mysql-server" package

Removed my previous line and edited the install task to do a check for debian.

I changed ever place it said php_version to php_ver to accurately tell the user what variable is used in the playbook.

Spelling error fix

Disable the default site of apache and nginx on demand

This creates a check for if the user has Debian or not.
In Debian, the package name for mysql is "default-mysql-server".

Misspelled "opereting system" for in the readme.
Change is just "operating".

Adds support for Debian 10 Buster

Pointed out by @aalaesar during review. In short, libmcrypt has been
obsolete since PHP 7.1 and removed since PHP 7.2. Therefore, we'll
preserve the installation of the package on older platforms
(specifically 5 & 7.0), but skip it on newer platforms (such as 7.2,
7.3). See for details [0].

Mostly it's the PHP version bump, 7.0 -> 7.3. One of the PHP packages
doesn't exist in the Buster repos, so added conditional logic to
preserve it by default, but omit specifically when PHP == 7.3.

Added support for Multi os
