[YulNaumenko]

Summary

Resolves #111804

In this PR was extended rules registry ability to specify rule task timeout, which could be useful for some rule types which expecting a log running rules.
Could be set in the rule type properties:

 const ruleType: AlertType<never, never, never, never, never, 'default', 'backToAwesome'> = {
      id: 'test',
      name: 'Test',
      actionGroups: [
        {
          id: 'default',
          name: 'Default',
        },
      ],
      defaultActionGroupId: 'default',
      ruleTaskTimeout: '13m',
      executor: jest.fn(),
      producer: 'alerts',
      minimumLicenseRequired: 'basic',
      isExportable: true,
    };

Added ability to configure default framework rule task timeout using Kibana config setting:
xpack.alerting.defaultRuleTaskTimeout

LGTM! Just a comment about allowlists and some wording suggestions for the docs/README

[ymao1]

Can we add this to the docker allowlist and also open a cloud PR for this setting?
