version 2.7.0 doesn't check well unsemver version for pre 5.3.0 check

[sylvainOL]

new version of neuvector helm is supposed to work with version < 5.3.0

the check is the following:

{{- $pre530 := false -}}
{{- if regexMatch "^[0-9]+\\.[0-9]+\\.[0-9]+" .tag }}
{{- $pre530 = (semverCompare "<5.2.10" $cleanVersion) -}}

with well semver formed version, it does work:

but with non semver version (like security patch one: 5.2.4-s1), it doesn't work and the charts use the >= 5.3.0 mode:

the check should "clean" the tag before doing the semverCompare:

{{- $pre530 := false -}}
{{- if regexMatch "^[0-9]+\\.[0-9]+\\.[0-9]+" .tag }}
{{- $cleanVersion := regexFind "^[0-9]+\\.[0-9]+\\.[0-9]+" .tag }}
{{- $pre530 = (semverCompare "<5.2.10" $cleanVersion) -}}
