Add composer allow-plugins to composer.json for Varbase and Varbase Project template to work with Composer 2.2.1 and later versions

Problem/Motivation

Composer 2.2.1 was released 2021-12-22
https://getcomposer.org/changelog/2.2.1
https://github.com/composer/composer/releases/tag/2.2.1

• Fixed plugin autoloading including files autoload rules from the root package (#10382)
• Fixed issue parsing php files with unterminated comments found inside backticks (#10385)

https://getcomposer.org/doc/06-config.md#allow-plugins

After updating the composer in local or in an automated testing you will face the following issue

composer/installers contains a Composer plugin which is currently not in your allow-plugins config. See https://getcomposer.org/allow-plugins
Do you trust "composer/installers" to execute code and wish to enable it now? (writes "allow-plugins" to composer.json) [y,n,d,?] y
y - add package to allow-plugins in composer.json and let it run immediately
n - add package (as disallowed) to allow-plugins in composer.json to suppress further prompts
d - discard this, do not change composer.json and do not allow the plugin to run
? - print help

A question to trust will show up for each used composer plugin in Varbase
