feat: add support for NetBox v2 API tokens

Auto-detect v2 tokens by their nbt_ prefix and use the Bearer
authorization scheme instead of Token. V1 tokens are unchanged.

Update api_token provider description to document v2 support and
add tests verifying the correct auth scheme is sent for each token type.
