FRW-2182 extend TimestampableBehavior with is_timestamp parameter to allow configuration of datetime type for created_at and updated_at

Behavior should be extendable on 2.0.0-beta2 (2.0.1-beta2) and 2.0.0-beta3 (2.0.1-beta3) versions.
Thank you.

1. Adjust field TimestampableBehavior::parameters

    /**
     * @var array<string, mixed>
     */
    protected $parameters = [
        'create_column' => 'created_at',
        'update_column' => 'updated_at',
        'disable_created_at' => 'false',
        'disable_updated_at' => 'false',
        'is_timestamp' => 'true',
    ];

3. Add method TimestampableBehavior::isTimestamp() :

    /**
     * @return bool
     */
    protected function isTimestamp(): bool
    {
        return $this->booleanValue($this->getParameter('is_timestamp'));
    }

3. Adjust method TimestampableBehavior::modifyTable() :

    /**
     * Add the create_column and update_columns to the current table
     *
     * @return void
     */
    public function modifyTable(): void
    {
        $table = $this->getTable();

        if ($this->withCreatedAt() && !$table->hasColumn($this->getParameter('create_column'))) {
            $table->addColumn([
                'name' => $this->getParameter('create_column'),
                'type' => $this->isTimestamp() ? 'TIMESTAMP' : 'DATETIME',
            ]);
        }
        if ($this->withUpdatedAt() && !$table->hasColumn($this->getParameter('update_column'))) {
            $table->addColumn([
                'name' => $this->getParameter('update_column'),
                'type' => $this->isTimestamp() ? 'TIMESTAMP' : 'DATETIME',
            ]);
        }
    }

Hey, I'm opening a PR with your code @maritechpro and will try to add some tests.

I would greatly appreciate this kind of changes. The propel diff are now nearly impossible to use due to thousands of detected diff that must be manually deleted from the result of the diff everytime.
For instance :

ALTER TABLE `table`

  CHANGE `created_at` `created_at` TIMESTAMP NULL,

  CHANGE `updated_at` `updated_at` TIMESTAMP NULL;
