Luan Nunes Utimura 34b130335f build-helm-charts: Fix --package option parsing 
When building helm charts, it has been observed that the preferred long
option for specifying packages, `--package`, isn't being recognized by
`getopt` as a valid option.

As a result, one must resort to the deprecated alternative `--rpm`.

Therefore, this change adds `package` as one of the long options for
`getopt`. And since it updates the parameters of this build script, it
also updates the help message of the `--os` parameter to match the other
scripts:

  * build-wheels/build-wheel-tarball.sh;
  * build-docker-images/build-stx-base.sh;
  * build-docker-images/build-stx-images.

Test Plan:
PASS - Build helm charts with --rpm
PASS - Build helm charts with --package

Closes-Bug: 2022090

[-r, --rpm <rpm-name>] [-i, --image-record <image-record>] [--label <label>]
[-p, --patch-dependency <patch-dependency>] [ --verbose ]
Options:
--os:
Specify base OS (valid options: ${SUPPORTED_OS_ARGS[@]})
-a, --app NAME:
Specify the application name
-A, --app-version-file FILENAME:
Specify the file containing version information for the helm
charts. By default we will search for a file named
$APP_VERSION_BASE in all git repos.
-B, --app-version VERSION:
Specify application (tarball) version, this overrides any other
version information.
-r, --package PACKAGE_NAME,... :
Top-level package(s) containing the helm chart(s), comma-separated.
Default: ${APP_NAME}-helm
--rpm PACKAGE_NAME,... :
(Deprecated) same as --package
-i, --image-record FILENAME :
Specify the path to image record file(s) or url(s).
Multiple files/urls can be specified with a comma-separated
list, or with multiple --image-record arguments.
Note: Files are in order of priority. Images may appear
in multiple files, the last image reference has higher
priority.
-l, --label LABEL:
Specify the label of the application tarball. The label
will be appended to the version string in tarball name.
-p, --patch-dependency DEPENDENCY,... :
Specify the patch dependency of the application tarball,
comma-separated
Multiple patches can be specified with a comma-separated
list, or with multiple --patch-dependency arguments.
--verbose:
Verbose output
