Mockery branch renamed from master to main.

[esurov]

composer install no longer works as mockery/mockery branch no longer exists. It's been renamed to main.

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires mockery/mockery dev-master, found mockery/mockery[dev-feature/refactor-internal-classes, dev-remove-comments-from-mock-pass, dev-feature/types, dev-mock-internals, dev-chore/add-blackfire, dev-main, dev-issue-1190/address-bc-changes-test-did-not-perform-any-assertions-error, dev-issue-1328/shouldnotreceive-is-overridden-by-invocation-count-methods, dev-feature/php82/mock-readonly-classes, 0.7.2, ..., 0.9.x-dev, 1.0.0-alpha1, ..., 1.6.x-dev, 2.0.x-dev] but it does not match the constraint. Perhaps dev-master was renamed to dev-main?

Also phpunit.xml was invalid. syntaxCheck attribute is not allowed:

  Warning - The configuration file did not pass validation!
  The following problems have been detected:

  Line 12:
