roachtest: bump min version for db-console/mixed-version-endpoints roachtest

Previously the mixed version roachtest would fail whenever test plans included
versions of crdb < 24.3. This was because a handful of /api/v2 endpoints were
added in 24.3 (and not backported), and so they would return 404s in the test
on versions prior.

This commit bumps the min version to 24.3.0.

Fixes: #150601, #148875, #149866
Release note: None
