Fix script to pick up correct zip

[jmazanec15]

Description

Fix find command to look in correct place. This broke because micro-benchmarks ends up producing a zip in the build/distributions folder.

Locally:

Without fix:

$ find "$(pwd)" -path \*build/distributions/*.zip
<PATH>/k-NN-1/micro-benchmarks/build/distributions/micro-benchmarks-2.14.0.0-SNAPSHOT.zip
<PATH>/k-NN-1/build/distributions/opensearch-knn-3.0.0.0-SNAPSHOT.zip

With fix

$ find "$(pwd)/build/distributions" -path \*.zip
<PATH>/k-NN-1/build/distributions/opensearch-knn-3.0.0.0-SNAPSHOT.zip
