Infex #461 Update opensearch instance type in AWS examples

[bkenez]

As defined in this ticket the instance type of AWS opensearch examples has been modified from t3.medium search to m7i.large.search

In addition, the default value for the dedicated_master_node of Opensearch clusters has been changed from m4.large.search to m5.large search. The reason for this is that the m5 version is available in all regions, at a consistently cheaper price than the m4 one.

Overall, looks good 👍.
Just need to install pre-commit locally and run it again to fix it.

pre-commit install
pre-commit run --all-files

for future changes in this repository you shouldn't have linting problems anymore.

There are a couple of README mentionings with examples where we could update the instance type as well.

Looking at e.g.

• https://github.com/camunda/camunda-tf-eks-module/blob/infex-461-update-instance-type/README.md?plain=1#L63
• https://github.com/camunda/camunda-tf-eks-module/blob/infex-461-update-instance-type/modules/opensearch/README.md?plain=1#L19

Fixed them, thanks for pointing it out!
And also now with pre-commit.
