General `error.type` definition should clarify that fully qualified exception type name should be used

What happened?

Description

Common definition of error.type doesn't mention that fully qualified name should be used (when exception type is recorded).

It's specifically important on Python where exception_type.__name__ is not qualified.

Expected Result

Here's how we recommend it in HTTP semconv

[1]: If the request fails with an error before response status code was sent or received, error.type SHOULD be set to exception type (its fully-qualified class name, if applicable) or a component-specific low cardinality error identifier.

TODO:

• [x] update error.type description - done in #945
• [ ] add per-language table on how to record exception.type (and error.type) see https://github.com/open-telemetry/semantic-conventions/pull/945#discussion_r1575408416

Semantic convention version

1.24.0
