Fix dependency version

We updated the queries dependency too early - reverted that change now.

Improve typing information

Enable fully typed mode in Psalm for generated repositories.

v0.12.2

Allow Symfony 6

PHP 8.1 compatibility for generated repositories

PHP 8.1 reported an error about "Could not check
compatibility" because SelectIterator was type
hinted before it was defined when generating
repositories.

Move to PHP8-only (with BC break)

• Rename Annotation directory to Attribute - this is a BC break
    (you will need to change the class imports in your entities)
• Remove annotation support and dependency on doctrine annotations
• Check all tests with Psalm and add better typing

Enable upserts to have complicated update clauses

insertOrUpdate did not accept all the possibilities of an
update clause so far - it had its own implementation on
how to parse the updates. We now use the exact same logic
as for update, enabling the same queries.

Support PHP8 attributes

Both annotations and attributes are supported, but attributes are the way forward and preferred.

Fix class finder for PHP8

PHP8 changed how namespaces and class names are composed, so
finding the correct namespaces and used classes is slightly
different.

v0.11

Upgrade queries dependency to 0.12

v0.10: Rename trait to populate entity properties

- Also fix multi repositories use case with no where
  query and only one repository
- Some configuration updates
