[docs-infra] Ignore classes tagged with @ignore

[cherniavskii]

We want to ignore some internal classes in Data Grid: mui/mui-x#11924 (comment)

Example:

Adding @ignore tag:

diff --git a/packages/mui-base/src/Badge/badgeClasses.ts b/packages/mui-base/src/Badge/badgeClasses.ts
index 6ed7dfc7e1..788e30067f 100644
--- a/packages/mui-base/src/Badge/badgeClasses.ts
+++ b/packages/mui-base/src/Badge/badgeClasses.ts
@@ -8,7 +8,10 @@ export interface BadgeClasses {
   root: string;
   /** Class name applied to the badge `span` element. */
   badge: string;
-  /** State class applied to the badge `span` element if `invisible={true}`. */
+  /**
+   * @ignore - do not document.
+   * State class applied to the badge `span` element if `invisible={true}`.
+   */
   invisible: string;
 } 

Results in the following diff:

diff --git a/docs/pages/base-ui/api/badge.json b/docs/pages/base-ui/api/badge.json
