Fix MatrixRecord bug with accepting objects as data value

[a-afsharfarnia]

Description

In the recent update to MatrixRecord, type hints were introduced to enhance code readability and maintainability (PR #77).

However, there's an opportunity to refine the type hinting for the $value parameter. Currently, it is specified as null|string|int, but in practice, it can take on a broader range of types, such as objects, booleans, etc. This becomes particularly relevant when utilizing EntityType in our import configuration, where the field type may necessitate an object value. The current solution limits this flexibility.

Steps to Test

1. Create an import configuration with an EntityType field.
2. Verify that the import process will be done successfully with the specified field.

@a-afsharfarnia can you change line 3 in .github/workflows/code_style.yml? It should be on: [ push, pull_request ], because now code style tests are frozen.
