Allow any drupal/paragraph_blocks:3.1

Problem/Motivation

Currently in the composer.json the following line prevents any bug-fix updates on drupal/paragraph_blocks

{
    "require": {
        "drupal/paragraph_blocks": "3.1.3"
    }
}

Proposed resolution

{
    "require": {
        "drupal/paragraph_blocks": "^3.1"
    }
}

Remaining tasks

Change the composer.json AND create a new release. (because composer.json can't be patched)
