Support rename from TaskRunner to Toolbox
Summary
Implements a function named ToolboxComponentName that will return "toolbox" if the Chart version is >= 5.4.0. Otherwise, it will return "task-runner".
Uses the Masterminds/semver version constraint check.
Will be required when gitlab-org/charts/gitlab!2094 (merged).
Changes can be reversed and hard-coded to toolbox
when all versions in CHART_VERSIONS are >= 5.4.0 (#386 (closed)).
Closes #384 (closed)
