Numbers may not have a leading zero

[dvirf1]

While reading through the Scanner class I noticed that it emits an error when non-zero numbers have a leading zero.
e.g 1, 3.14 and 42d are valid literals, and 01, 03.14, 042d, 00042d are invalid, resulting in a compilation error:

Non-zero numbers may not have a leading zero.

This makes sense, and according to the main objectives of Scala 3 it is expected that this behavior will be consistent with zero numbers.
e.g 0, 0.0, 0d should be valid and 00, 00.0, 00d should be invalid.
When trying this in the REPL, this is already the behavior (which makes since because isDigit('0') yields true), and only the message ("non-zero numbers ..") is wrong.
