doc: Remove section on FIPS workaround for frontend assets

Thanks to https://gitlab.com/gitlab-org/gitlab/-/merge_requests/78581,
Webpack no longer attempts to use MD4 or MD5 hashes. The GDK can be
used without this static asset compilation workaround. Tested on a
FIPS-enabled, RedHat Enterprise Linux (RHEL) 8 system.

-### Working around broken frontend asset compilation
-
-A known bug affects asset compilation with FIPS mode enabled: [issue #322883](https://gitlab.com/gitlab-org/gitlab/-/issues/322883).
-Until this is resolved, working on frontend issues is not feasible. We can still
-work on backend issues by compiling the assets while FIPS is disabled, and
-placing GDK into [static asset mode](https://gitlab.com/gitlab-org/gitlab-development-kit/-/blob/main/doc/configuration.md#webpack-settings):

-1. Modify your `gdk.yml` to contain the following:

-     port: 3808
-     static: true
-   ```

-1. In the GitLab repository, apply this patch to prevent the assets from being
-   automatically deleted whenever GDK is restarted:

-   ```diff
-   diff --git a/scripts/frontend/webpack_dev_server.js b/scripts/frontend/webpack_dev_server.js
