web: Use sha1 filter instead of md5 (#1386)

This was fixed in 6cae8df but the task/web split rebase didn't apply this
to the web deployment.
This prevents to deploy the operator when FIPS is enabled.

{"msg": "An unhandled exception occurred while running the lookup plugin
'template'. Error was a <class 'ValueError'>, original message:
[digital envelope routines: EVP_DigestInit_ex] disabled for FIPS"}
