build(deps): Bump github.com/open-policy-agent/opa from 1.21.0 to 1.21.1 in /core

[dependabot]

Bumps github.com/open-policy-agent/opa from 1.21.0 to 1.21.1.

Release notes

Sourced from github.com/open-policy-agent/opa's releases.

v1.21.1

This release fixes a compiler regression introduced in OPA v1.21.0.

Fix some … in/every in comprehensions nested in object and set literals (#9280)

A comprehension using some … in or every in its body, nested inside an object or set literal, was wrongly treated as ground, so the compiler skipped rewriting it. some … in then failed with rego_unsafe_var_error; every caused a compiler panic:

package example
p := {"k": [r.a | some r in input.xs]}           # rego_unsafe_var_error: var r is unsafe
q := {[1 | every x in input.xs { x > 0 }]}       # panic

Array literals weren't affected, and neither were literals that contain some other non-ground term.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.

Patch bump. CI green on head; also validated locally on main + all open Dependabot bumps combined: per-module GOWORK=off tidy/build/vet/test across every go.work module (cortex-cpex with -tags cpex). Merge before #1303 (adjacent lines in core/go.mod).
