fix #48 Render the execution duration with an overridable template

[njoubert-cleverage]

Description

Fixes #48

The duration format of the executions list was hard-coded in ProcessExecutionCrudController::configureFields() (formatValue() callback): changing it required overriding the controller.

Changes

• New @CleverAgeUiProcess/admin/field/duration.html.twig template: renders ProcessExecution::duration() with the %H hour(s) %I min(s) %S s format (translated in the messages domain, as before); the EasyAdmin label/null template for a running execution (as before). The format can be changed by overriding the template (templates/bundles/CleverAgeUiProcessBundle/admin/field/duration.html.twig) or by translating the format.
• ProcessExecutionCrudController: the duration field uses this template. The $translator constructor argument (only used for this format) is no longer used: kept for BC, deprecated (PHPDoc), will be removed in 4.0. Its binding in config/services/controller.yaml is unchanged.
• rector.php: RemoveUnusedConstructorParamRector skipped on ProcessExecutionCrudController (it removed the deprecated argument); PHPStan constructor.unusedParameter ignored on its constructor.
• Reference doc (04-process_executions_and_logs.md): how to change the format, with an override example.
• CHANGELOG: The duration format should be defined in the template to avoid having to override the controller #48 entry (unreleased).

Tests

• ProcessExecutionCrudTest::testDuration: a finished execution displays 00 hour(s) 00 min(s) 00 s, a running one Null.
• 296 tests OK. PHPStan, PHP-CS-Fixer, Rector, Twig-CS-Fixer OK.

Requirements

• Documentation updates
  • Reference
  • Changelog
• Unit tests

Breaking changes

• None. Deprecation: the $translator argument of ProcessExecutionCrudController::__construct() is no longer used, it will be removed in 4.0.
