[Xray] Random execution-service-aes-key breaks automation

BUG REPORT

Version of Helm and Kubernetes:

Which chart:
Xray helm chart > 103.43.1

What happened:
When using argocd to continuously check the helm chart and keep it in sync it tries to change the execution-service-aes-key key every time it runs. This is because the key is randomly generated every time it runs.

What you expected to happen:
To create a "changeme" value that can be changed in the values.yaml just like the joinkey and masterkey.

How to reproduce it (as minimally and precisely as possible):

helm template xray  -f values.yaml . > output.yaml
helm template xray  -f values.yaml . > output2.yaml
diff output.yaml output2.yaml 
246c246
<   execution-service-aes-key: "dThvNXpGb09JQWZ1WTdQdVU0NlZSamUxek8xbmFHYkc="

>   execution-service-aes-key: "MEZFS0NZNlJHYXhVZ0lpYmZqNVNWM05tUllWVW11R3U="
