Subject: [PATCH] Update regular-expression-patterns.md

Even the Scala 3 requires curly braces when I run it in Scastie.

Is this a problem with Scastie's default build [which uses Scala 3] or with the sample code -- which I just fixed?

I'm guessing based on my 0 experience with Scala that use of the imported function causes an inference which requires the curly braces.

Kept getting  “error: recursive value $t needs type” in Scastie using Scala 3 without this fix.  Took it as a learning exercise to find out why.
