Add release helper script.

[apognu]

Summary by CodeRabbit

• Chores
  • Added a POSIX shell release helper to select backend and frontend versions, with optional Motiva version support.
  • The helper fetches and checks out the specified backend/frontend branches and exports the chosen version values.
  • Automatically updates both release and development compose configuration with the selected image tags, including the Motiva service image only when provided.
  • Includes validation and strict error handling to prevent incomplete or invalid release setups.

Poem

Versions march where release winds blow,
Backend and frontend in orderly flow.
Motiva joins when called by name,
Compose tags kindle the deployment flame.
A small shell script makes all things align.

Inline comments:
In `@contrib/release.sh`:
- Around line 10-25: Harden the option parsing loop in contrib/release.sh: for
each --backend, --frontend, and --motiva case, validate that a following
argument exists before reading it or executing shift 2, and reject missing
values with an error. Update the final backend and frontend validation to
require the release-tag format vX.Y.Z rather than merely non-empty values, while
preserving the existing unknown-option handling.
- Around line 1-4: Update the contrib/release.sh shell setup by removing set -o
pipefail while retaining POSIX /bin/sh compatibility, and quote the BACKEND and
FRONTEND references in the git checkout commands to prevent word splitting.
- Around line 28-30: Quote the BACKEND and FRONTEND expansions in the git
checkout commands within the release script to ensure each revision is passed as
a single argument, while preserving the existing repository and command flow.
