Indexers packages fails to built for main branch due to the absence of VERSION file

[Rebits]

Description

In Nightly 27/02/2025 it has been detected that indexers packages are failing to construct:

Action: https://github.com/wazuh/wazuh-indexer/actions/runs/13555975035/job/37890237857

Run echo "version=$(<VERSION)" >> "$GITHUB_OUTPUT"

/home/runner/work/_temp/0cccb385-9ace-49b5-ae41-f68eb14bd1f3.sh: line 1: VERSION: No such file or directory

Error: Process completed with exit code 1.

The main branch no longer contains a VERSION file. Instead, it now has a VERSION.json file. This action should be adapted accordingly.
