console-plugin-template currently uses PatternFly 4 and dynamic plugin sdk versions less than 1.  Now that dynamic plugin sdk version 1 is out, we should upgrade to the latest versions.

AC:

• update https://github.com/openshift/console-plugin-template/blob/main/package.json to use the following:

    "@openshift-console/dynamic-plugin-sdk": "^1.0.0",
    "@openshift-console/dynamic-plugin-sdk-webpack": "^1.0.0",

    "@patternfly/react-core": "^5.1.1",

    "@patternfly/react-icons": "^5.1.1",
    "@patternfly/react-styles": "^5.1.1",

• add icon example into the template's ExamplePage
• Incorporate changes from https://github.com/openshift/console-crontab-plugin/pull/22/files#diff-a2fcf2d017f0935b302e40601bbaf3e16571ac6014490f24df26e83575f29467

Note: Document the PF5 upgrade steps in https://issues.redhat.com/browse/CONSOLE-3908
