Ensure filtered_attributes and filtered_optimistic are also regex

[sjorge]

There was some further discussion on #12988 after it got merged pointing out that filtered_cache, unlike the other filtered_* is regex based.

Having it as a regex is actually more flexible, so this PR updates filtered_attributes and filtered_optimistic to also be regex based.

For testing I kept my exiting config unchanged and noticed everything still worked, then I added ^ and $ anchors and everything also still worked, providing a 'bare' attribute name mostly will still work fine, unless something like 'color' is provided it will now match attribute containing color in the name.

Further testing nothing broke on a test network with a single bulb:

• verified filtered_attributes still removes the attributes from the publish
• verified filtered_optimistic did not trigger optimistic updates for 'state' and 'brightness' (remove reporting, update either and observe no change + restore reporting, update either and get one update triggered by the attributeReport)
• verified filtered_cache (not touched) still removed attributes from being cached

tests pass even without modifying because they were all unique named properties.

Redid the same tests
