fix(supportbundle): include default redactor spec in support bundle command

[xavpaice]

What this PR does / why we need it:

The support bundle command API (GetSupportBundleCommand) was generating a kubectl support-bundle command that omitted the default redactor spec. The in-cluster collection path already includes this default redactor via CreateSupportBundleDependencies, so the CLI command was inconsistent and could expose IP addresses that should be redacted by default. This PR adds the default redactor URI to the generated command so both paths apply the same redactors.

Which issue(s) this PR fixes:

https://app.shortcut.com/replicated/story/139424

Does this PR require a test?

Yes, a unit test was added in pkg/supportbundle/supportbundle_test.go to verify the generated command includes the default redactor spec.

Does this PR require a release note?

Bug fixes:

Fixed an issue where the support bundle command returned by the KOTS admin console did not include the default redactor spec, causing IP addresses to not be redacted when the command was run outside of the cluster.

Does this PR require documentation?

NONE
