docs: Add documentation for new BASH syntax
Metadata
Current evaluation
Adds 12 lines documenting snapd 2.77+ ${VAR:+value} and ${VAR:-default} expansion; approved by two reviewers, no failures, but build, lint, and test checks remain pending.
Suggested action: needs review
Reason: The one-file, +12-line documentation diff has two approvals and no failing checks. However, build, lint, fast-test, minimum-dependency, and slow-test checks are still pending, and the author confirmed that make lint && make test was not run, so final merge readiness is not yet established.

Issue body
