Magento2 Configurator Versions Save

Fixes for the product import components after updating FastSimpleImport to version 2.0.0: #131

• Update the version of firegento/fastsimpleimport to provide better support for PHP 8 (#128 Thanks @NathanDayFE)
• Fix the return types for Symfony Console commands on the later releases of Magento (#130 Thanks @matmarchant)
• Improve PHP 8 compatibility (#126 Thanks @benjamenhogben)
• Allow the admin interface locale to be specified on the admin user component (#123 Thanks @franckcharpentier)

• Bring in the latest version of firegento/fastsimpleimport
• Documentation fix (thanks @frqnck)

• Enhances the detection of the file type with remote sources
• Improves the product import by running the data through the validator and removing any failing products

• Adds feature to auto-encrypt any configurations using the Encrypted back-end model, even is the encryption flag isn't stated in the YAML. encryption can still be manually used to properties with non-existent/different backend models as appropriate.

New sequence component allowing you to define sales sequences for sequences that have not been created.

Fixes a few bug with the catalog price rules importer. First of all, it had a completely irrelevant class being used as a processor which was never going to work. This is sorted now. Sorry!

We also noticed some issues with this component when installing on 2.3.4 which we've fixed.

Configurator 3.0.0 is here and is threatening to break down Magento walls like the Kool-Aid man. If you have any custom components, you'll need to refactor them to use the ComponentInterface. Check out the highlights below.

• No more object manager to load components. Components are now loaded using di.xml
• Each component is now a standalone class and implements the ComponentInterface.
• As a component no longer extends from a specific parser (e.g. CSV) your source can now be in any one of CSV, YAML, or JSON.
• Sources can be loaded from a remote URL
• You can pass in the --ignore-missing-files (-i) flag into configurator:run to ensure that missing files are skipped #84
• Fixed #93

Fix a warning on the products when trying to call count() on class members with no value.
