fix: maps axon ports correctly

[grantdfoster]

Description

After release, noticed a bug on mainnet where the ports were not being correctly mapped to the axon, even though the Makefile was passing --axon.port correctly. The likely culprit is/was an upgrade to bittensor, and the bug was not caught until running multiple axons on mainnet.

Updated code for the miner and validator base:

self.axon = bt.axon(
  wallet=self.wallet, config=self.config, port=self.config.axon.port
)

By explicitly passing an axon port, we resolve the issue where an axon is trying to be served by the default ports, 0891 for miners and 0892 for validators.
