.[char] as a numeric literal prevents errors from being raised

• d isn't throwing an error
• when d is enabled, it hides errors b would raise

The textmate scope is constant.numeric.integer.powerquery for the section before the .

Environment

powerquery.vscode-powerquery 0.1.19

To Reproduce

[<number>].<char><anything>

• It's . followed by a single text character that triggers it. The rest can be anything.
• the prefix is optional
• It occurs with values outside the hex literal range (non-a-f)

let   
    a = .z
in
    a

Expected Behavior

PBI returns an Token Comma Expected error

Start by reproducing the provided Power Query example with .z and inspect the TypeScript handling of numeric literals and the following text character. Confirm that the invalid form reports the expected Token Comma Expected error and no longer suppresses related errors.
