[BUG] adminPassword is required for versions below than 2.12.0

[gaiksaya]

What is the bug?

In order to accomodate security plugin tool changes, #86 was added as a feature. However, the logic resolving 2.3.0 as greater than 2.12.0. Mathematically it is correct but semver-wise its wrong.

How can one reproduce the bug?

Clone the repo at the above PR commit and try deploying using below command:

npm run cdk ls -- --context securityDisabled=false \
--context minDistribution=false --context distributionUrl='https://artifacts.opensearch.org/releases/bundle/opensearch/2.3.0/opensearch-2.3.0-linux-x64.tar.gz' \
--context cpuArch='x64' --context singleNodeCluster=false --context dataNodeCount=3 \
--context dashboardsUrl='https://artifacts.opensearch.org/releases/bundle/opensearch-dashboards/2.12.0/opensearch-dashboards-2.12.0-linux-x64.tar.gz' \
--context distVersion=2.3.0 --context serverAccessType=prefixList --context restrictServerAccessTo=pl-f8a64391 --context additionalConfig='{"cluster.name": "cdk"}' --context mlNodeCount=1 \
--context use50PercentHeap=true
No VPC-Id Provided, a new VPC will be created

Error:

~/opensearch-project/opensearch-cluster-cdk/lib/infra/infra-stack.ts:212
      throw new Error('adminPassword parameter is required to be set when security is enabled');
            ^
Error: adminPassword parameter is required to be set when security is enabled

What is the expected behavior?

It should not throw and error for versions less than 2.12.0
