tests: Add Taproot soft fork status to getblockchaininfo test

This commit updates the `rpc_blockchain.py` functional test to include the Taproot soft fork status in the `getblockchaininfo` RPC call. The Taproot soft fork is defined using the BIP9 activation mechanism with specific start and timeout times. The test verifies that the Taproot soft fork is correctly reported as "defined" and not yet active.

Changes include:
- Adding Taproot soft fork details to the expected `softforks` field in the `getblockchaininfo` test.
- Ensuring the test checks for the correct status, start time, timeout, and activation state of the Taproot soft fork.

This update ensures that the `getblockchaininfo` RPC call accurately reflects the status of the Taproot soft fork, which is crucial for testing and validation purposes.
