Benoit Tigeot d97953f101 Pin actions and tighten workflow permissions (#3954)
* ci: Reduce chance of installing corrupt packages

* ci: prevent credential leakage from checkout steps

Add `persist-credentials: false` to all `actions/checkout` calls across
22 workflow files. Without this, the GitHub token used for checkout is
written into `.git/config` and remains accessible to all subsequent steps
and any uploaded artifacts (artipacked finding).

* ci: prevent template injection from github context in run steps

`${{ github.* }}` expressions used directly inside `run:` blocks are
expanded before the shell sees them. A crafted value (e.g. a tag name
containing shell metacharacters) would execute arbitrary code.

Move the values into `env:` variables (e.g. GITHUB_EVENT_RELEASE_TAG_NAME,
GITHUB_ACTOR) and reference them as `${VAR}` in the shell, so the runtime
never interprets them as code (template-injection finding).

* ci: prevent injection in yq commands via release tag name

`${{ github.event.release.tag_name }}` was interpolated directly into
yq `cmd:` inputs. A crafted tag name could inject shell commands since
the expression is expanded before the action runs. Use yq's `strenv()`
with an `env:` variable instead so the value is always treated as data.

* ci: pin all GitHub Actions to full commit SHAs

Actions pinned to mutable tags (e.g. @v6, @main) can change under us if
the upstream repo is compromised or tags are moved, enabling supply-chain
attacks. Pinning to the full 40-char commit SHA locks the exact code that
runs. Version tags are preserved as inline comments (e.g. # v6.0.2) for
readability and Dependabot compatibility.

Used `pinact` for standard tagged versions; remaining branch-based
references (mikefarah/yq, jlumbroso/free-disk-space,
project-stacker/stacker-build-push-action, aquasecurity/trivy-action)
resolved manually via the GitHub API.

* ci: slow down GitHub Actions dependency updates to biweekly

Dependabot has no native biweekly interval. Combining weekly checks with
a 14-day cooldown achieves the same effect: Dependabot scans every Monday
but won't open a PR for a new action version until 14 days after release,
giving the ecosystem time to stabilize before we adopt it.

* ci: group all Dependabot updates into single PRs per ecosystem

Without groups, Dependabot opens one PR per dependency. With `patterns: "*"`,
all Go module bumps land in one PR and all GitHub Actions pin updates in
another, reducing review noise.

* ci: restore credential persistence for helm-charts push

`persist-credentials: false` was too broad — the helm-charts checkout
uses HELM_PUSH_TOKEN specifically so the subsequent `git push` can
authenticate. Only the main repo checkout should have credentials disabled.

* ci: use --password-stdin for oras login

Passing the token via `-p` exposes it in process listings and debug
logs. Piping via stdin is the standard secure pattern for CLI auth.

* ci: pin actions to versioned release SHAs

jmgilman/actions-generate-checksum: v1 branch HEAD -> v1.0.1 release
mikefarah/yq: arbitrary master HEAD -> v4.52.5 release
