Bug - Multiple File Upload - `progressVariant` is limited to "success|warning|danger" bar colors and the BLUE color is not possible

Describe the problem
The component https://v5-archive.patternfly.org/components/file-upload/multiple-file-upload does not allow to have BLUE bar colors as mentioned in the Design Guidelines https://v5-archive.patternfly.org/components/file-upload/multiple-file-upload/design-guidelines/

The guidelines indicate that the BLUE color can be used for "In Progress" statuses. However, the current progressVariant does not allow you to set a value so the progress bar becomes BLUE

How do you reproduce the problem?
Provide steps to reproduce. A codesandbox demonstrating the problem is appreciated.

Expected behavior

• progressVariant should allow a value for BLUE or
• If progressVariant=null|undefined then BLUE should be applied automatically

Multiple File Upload コンポーネントから始め、progressVariant prop がプログレスバーの色をどのように制御しているかを追跡します。コンポーネントの動作をリンクされたデザインガイドラインと比較し、追加の blue 値、または null や undefined に対するデフォルト値が適切かどうかを確認します。完了の条件は、進行中のアップロードが青で表示され、既存の success、warning、danger バリアントが引き続き機能することです。
