Remove unnecessary space from application.yml of GMS

[mmmeeedddsss]

There was an extra space in the application.yml file on the definition of elasticsearch.index.numRetries. Even we couldn't see that this cause any issue, we still wanted to make a change for the consistency in the format of the file.

See a broader context from the slack thread around an issue we have with overriding the elasticsearch.index.numRetries config by passing the env var ELASTICSEARCH_INDEX_BUILDER_NUM_RETRIES
