Fix ci version parsing script

[finnegancarroll]

Description

This build.yml script is slightly off due to the extra '-' in "asynchronous-search".
Current output:

plugin version plugin_version qualifier docker_version
(opensearch-asynchronous-search-3.0.0.0-SNAPSHOT.zip) (search) (search) (-3) (search-3)
/home/runner/work/asynchronous-search/asynchronous-search
-rw-r--r-- 1 runner docker 980985 Nov  4 20:14 ./opensearch-asynchronous-search-3.0.0.0-SNAPSHOT.zip
Error response from daemon: manifest for opensearchstaging/opensearch:search-3 not found: manifest unknown: manifest unknown

Off by one error fixed:

plugin=opensearch-asynchronous-search-3.0.0.0-SNAPSHOT.zip
version=`echo $plugin|awk -F- '{print $4}'| cut -d. -f 1-3`
plugin_version=`echo $plugin|awk -F- '{print $4}'| cut -d. -f 1-4`
qualifier=`echo $plugin|awk -F- '{print $5}'| cut -d. -f 1-1`

echo $version
3.0.0
echo $plugin_version
3.0.0.0
echo $qualifier
SNAPSHOT
