Backport 10443bd from #1030

[Hailong-am]

@r1walz DCO check failed, can you check you github email address matches with local git config email address?

[r1walz]

Hi, @Hailong-am. I see that DCO sign-off by github bot is not included in the commit msg:

Change ...

  1. 'Close indices' to 'Close'
  2. 'Open indices' to 'Open'
  3. 'indices' to 'indexes'
  4. Sample slack webhook to meet current validation

... to match current tech writing guidelines.

// missing github bot sign-off

It's usually present like this: opensearch-project/OpenSearch#12115
