Pattern fix

[elai-shalev]

Closes https://issues.redhat.com/browse/FLPATH-1920

These changes were tested incrementally.

(1) Workflows with '.' in their name could be build but did not show on RHDH for error 1 below
(2) Workflows with Capital letters and numbers at the start could not be build with argocd for error 2 below.
(3) Hyphens are allowed in argocd and k8s, but are prohibited in workflows created because of using java.

Eventually the field of names for "workflows created by software templates, including custom java code, deployed by argocd and run on RHDH" are of names that have a lowercase alphabetical start, no hyphens, no periods, and all other chars being lowercase alphanumerical.

Errors:
(1)

     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])?''))'
