Fix .helmignore example pattern matching template directories

[Copilot]

The example pattern */*/temp* matches any path segment containing "temp", including templates/. This breaks nested chart rendering when users copy the example.

Changes

• Replace temp* → draft* in glob pattern examples
• Update comment: "Match draft files two levels deep (e.g., foo/bar/draft123)"
• Applied to all doc versions and i18n (en, ko, uk, zh)

Example

Before:

# Match any file under subdir matching temp*
*/temp*

*/*/temp*
temp?

After:

# Match any file under subdir matching draft*
*/draft*

# Match draft files two levels deep (e.g., foo/bar/draft123)
*/*/draft*
draft?

The new pattern demonstrates the same glob matching behavior without colliding with Helm's templates/ directory.

This section details on the original issue you should resolve

<issue_title>Helm ignore file temp example</issue_title>
<issue_description>In the .helmignore file example (https://helm.sh/docs/chart_template_guide/helm_ignore_file/), there are a couple of lines in the example file that caused issues in our nested Helm charts:

`# Match any file under subdir matching temp*
/temp

//temp*`

These lines caused our nested Helm charts to not render correctly as the //temp* matched the subchart templates folder. Took quite a bit of head scratching to figure this out.

Thank you!</issue_description>
