[Issue] Set default indexer mode to 'schedule'

[m2-assistant]

This issue is automatically created based on existing pull request: #36347: Set default indexer mode to 'schedule'

Description

It is recommended that indexers be in the schedule ("Update by Schedule") mode, and not realtime ("Update on Save") mode. However, when Magento is installed for the first time, all indexers are by default in the "wrong" mode. This pull request changes the default for new indexers to be in the expected / recommended mode.

This change will not impact any existing indexers and therefore existing websites should not notice any impact from this change. If a module with an indexer is installed on an existing website, it will be created with the new default mode: {{{}schedule{}}}.

Manual testing scenarios

1. Install Magento anew
2. Navigate in the admin to System -> Tools -> Index Management
3. Notice the colour of the "Mode" column. Before this change, these were all red, indicating an error/problem; after this change these are all green, indicating that all is well.

Hi @fredden,

Thanks for your Contribution!!

As per the requirement of https://jira.corp.adobe.com/browse/AC-6975 we delivered ‘Indexer default mode was schedule after Magento installation only’ and was not working when we install third-party Indexer(Custom Indexer) as default mode was still on save with third-party Indexer(Custom Indexer)
With new changes which are delivered in scope of https://jira.corp.adobe.com/browse/AC-11421 , if we install Magento or install third party Indexer(Custom Indexer), default mode will be schedule by default. It should resolve the issue raised in #36347 as well.
