docs: Update docstring for strict flag to make it unambiguous

[anubhav756]

The previous docstring for the strict parameter in the load_toolset method could be interpreted ambiguously. This change clarifies that when strict=True, an error is raised if any loaded tool instance fails to utilize all of the applicable parameters or auth tokens that were provided globally to load_toolset.

The original phrasing "fails to utilize at least one provided parameter" could have been misconstrued to mean an error only occurs if a tool uses none of the provided parameters. The updated phrasing "fails to utilize all of the given parameters or auth tokens" more accurately reflects the implemented behavior: each tool must exhaustively use all relevant configurations passed to load_toolset when in strict mode.

Note

Note that neither strict=False nor strict=True mode in load_toolset will inherently identify a tool within the set that is loaded but does not (and perhaps is not intended to) utilize any of the globally provided auth_token_getters or bound_params.

For instance, if a user wishes to validate the presence or specific configuration of such a "passively" configured tool (i.e., one that doesn't consume any of the globally provided configurations during the load_toolset call), a different approach is needed. In this scenario, the user would need to iterate through the tools individually after they are loaded and use methods like add_auth_token_getters() and/or bind_params() on a per-tool basis. This allows for checks of compatibility (e.g., whether a specific tool can accept a certain auth token or bound parameter, which would raise a ValueError if it's an unknown or inapplicable configuration for that particular tool) or to confirm expected behavior when such configurations are applied post-loading.

Eg.

tool = client.load_tool("my-passive-tool")

for auth_src, auth_token_getter in auth_token_getters.items():
    try:
        tool.add_auth_token_getter(auth_src, auth_token_getter)
    except ValueError as e:
        # tool did not use auth_src
