Log Message:
opa: Update to 0.54.0

Changes:
v0.54.0
This release focuses on bug fixes, but also includes some improvements
to the SDK and commandline.

Note: This will be the last OPA release to support building with Golang
1.18. (Golang 1.21 is expected to be released in August. Keeping the
support for 1.18 is blocking OPA from upgrading OpenTelemetry.)
