fix: increase iceberg retries in integration tests

[nicor88]

Description

The iceberg retries integration test is the most problematic. Sometimes, it passes, and sometimes, it does not.
Currently the test dues 10 parallel inserts. The idea of this PR is to increase num_iceberg_retries to a value big enough, to allow the test to pass.

@mikealfare @colin-rogers-dbt FYI.

Input required and not supplied: aws-region

Integration tests seem to be failing because there is a missing region @mikealfare

I believe that the issue is because here, my user (and every other user that contribute) don't have access to the variable.
If the variable is set on your organization level, I cannot certenly use it. But if the variable is set on the repo level, I should be able to use it - as it used to be in the old dbt-athena repo.

The region is there. This looks like it's related to the aws-creds action. It started failing for me after last night for v2, but v4 passes. I have another PR that was affectd that has that fix. So when I get that merged in, I'll sync this PR and all should be fine

@mikealfare any updates here? Integrations tests seems still not working, even after merging the latest from the main branch
