feat: update bare metal profiles to trustee-chart v0.6.*

Update chartVersion from 0.5.* to 0.6.* to align with trustee-chart
PR #30 which introduces BREAKING CHANGE: firmware reference values
consumed as single JSON blob instead of multi-key secret.

Both profiles already have kbs.baremetal.enabled: "true" set, enabling
firmware reference value enforcement when values are present in Vault.
