Remove abort from the abort signal

[orta]

This code clashes with the abort signal in node's dts, making it not possible to have both DOM and node in the same project:

../node/globals.d.ts(72,13): error TS2403: Subsequent variable declarations must have the same type. Variable 'AbortSignal' must be of type '{ new (): AbortSignal; prototype: AbortSignal; abort(reason?: any): AbortSignal; }', but here has type '{ new (): AbortSignal; prototype: AbortSignal; }'.

Logs

The automation during the deploy process to this repo should ave persisted the comment, but didn't because of the new reason param
