fix(helmfile): move the merge request IID to the end of the Release.Name
The Release.Name must follow the following spec:
a DNS-1035 label must consist of lower case alphanumeric characters or '-',
start with an alphabetic character, and end with an alphanumeric character
(e.g. 'my-name', or 'abc-123', regex used for validation is
'[a-z]([-a-z0-9]*[a-z0-9])?')]
