Part of https://github.com/stackabletech/issues/847

Update pre-commit Workflow

Note

The pre-commit config and workflows need to be kept up-to-date to ensure
usage of recent tooling versions. This requires some manual work in this
repository.

• Update python-version in local and templated pr_pre-commit.yml workflow
• Update hook refs in local and templated .pre-commit-config.yaml file
• Update Hadolint version in the config/versions.yaml file

Update Rust Toolchain

Note

During a Stackable release we need to ensure that every product operator uses
the latest Rust toolchain (used by us). To keep the toolchain in sync across
all our operators, we update the version centrally in this repository.

Tasks

• Run niv update and test via make run-dev
• Update stable Rust toolchain in the config/versions.yaml file.
• Update nightly Rust toolchain in the config/versions.yaml file (Keep in sync across this,
  operator-rs and docker-images).
• Update Rust toolchain in UBI10 and stackable-base images
• Update cargo-cyclonedx and cargo-auditable in UBI10 and stackable-base images
• Generate downstream PRs using the "Generate Downstream PRs" action. Use the following title for downstream PRs: chore(template): Updates for SDP YY.M.X.
• Search for PRs and add them to the list below.
• Add the release/YY.M.X label to the downstream PRs and continue to merge them. See below for more details.
