9.2.1/9.1.4 hec token not created when providing env var SPLUNK_HEC_TOKEN

[mkolasinski-splunk]

Running:
docker run -it -e SPLUNK_START_ARGS=--accept-license -e SPLUNK_PASSWORD=**** -e SPLUNK_HEC_TOKEN="testtoken" -p 8100:8000 -p 8188:8088 -p 8189:8089 --platform=linux/amd64 splunk/splunk:9.2.1 start
Results in spinning up Splunk container, but HEC token is not created

Issue confirmed on Splunk 9.1.4 as well.

On previous releases of Splunk HEC token is created properly, i.e. on Splunk 9.1.3:
docker run -it -e SPLUNK_START_ARGS=--accept-license -e SPLUNK_PASSWORD=**** -e SPLUNK_HEC_TOKEN="testtoken" -p 8000:8000 -p 8088:8088 -p 8089:8089 --platform=linux/amd64 splunk/splunk:9.1.3 start
Results in:

Same issue when specifying hec in default.yml
