RFR: 8355725: SPEC_FILTER stopped working

Wed May 28 00:11:02 UTC 2025

>From the bug description:

The SPEC_FILTER make variable is meant to be used to create small documentation bundles that just contain some selected files. Example usage:

`make docs-specs-zip SPEC_FILTER="%-jls.md copyright.html %logo.gif resources"`

The fix for [JDK-8349143](https://bugs.openjdk.org/browse/JDK-8349143) caused the feature to stop working: no matter what the filter variables says, all the specs get built. This is a regression, old behavior needs to be restored.
