[documentation]: remove auto-generated configuration reference

[0x009922]

Description

This PR removes auto-generated configuration reference and everything related to it.

The motivation is to make one step forward towards the new reference (hyperledger-iroha/iroha-2-docs#392).

After merge of this PR, there will be no configuration reference available for some time. We decided that it is fine and will streamline further process according to the RFC (#2585).

Should be reviewed and merged after:

• [fix] #4030, #4063, #4064, #4079: re-architect logger and dynamic configuration #4100
