Description

Change master nomenclature: Change master (mostly Github link) to main in docs and comments.

The only code using master nomenclature is in OpenSearch API call which doesn't seem have alternative clusterManager class or method:

RestQuerySettingsAction:
    final ClusterUpdateSettingsRequest clusterUpdateSettingsRequest =
        Requests.clusterUpdateSettingsRequest();
    clusterUpdateSettingsRequest.timeout(request.paramAsTime(
        "timeout", clusterUpdateSettingsRequest.timeout()));
    clusterUpdateSettingsRequest.masterNodeTimeout(request.paramAsTime(
        "master_timeout", clusterUpdateSettingsRequest.masterNodeTimeout()));

The following master in doc link are also not changed due to main branch missing:

./plugin/src/main/java/org/opensearch/sql/plugin/rest/RestQuerySettingsAction.java:82:    clusterUpdateSettingsRequest.masterNodeTimeout(request.paramAsTime(
./plugin/src/main/java/org/opensearch/sql/plugin/rest/RestQuerySettingsAction.java:83:        "master_timeout", clusterUpdateSettingsRequest.masterNodeTimeout()));

np. master in github links can usually be replaced with HEAD, so it always points to latest commit on the default branch even if default branch changed. but i think it's not necessary
