* fix: remove kwargs from all (except mysql & pg) RagTools
The agent uses the tool description to decide what to propagate when a tool with **kwargs is found, but this often leads to failures during the tool invocation step.
This happens because the final description ends up like this:
```
CrewStructuredTool(name='Knowledge base', description='Tool Name: Knowledge base
Tool Arguments: {'query': {'description': None, 'type': 'str'}, 'kwargs': {'description': None, 'type': 'Any'}}
Tool Description: A knowledge base that can be used to answer questions.')
```
The agent then tries to infer and pass a kwargs parameter, which isn’t supported by the schema at all.
* feat: adding test to search tools
* feat: add db (chromadb folder) to .gitignore
* fix: fix github search integration
A few attributes were missing when calling the .add method: data_type and loader.
Also, update the query search according to the EmbedChain documentation, the query must include the type and repo keys
* fix: rollback YoutubeChannel paramenter
* chore: fix type hinting for CodeDocs search
* fix: ensure proper configuration when call `add`
According to the documentation, some search methods must be defined as either a loader or a data_type. This commit ensures that.
* build: add optional-dependencies for github and xml search
* test: mocking external requests from search_tool tests
* build: add pytest-recording as devDependencie
