[PATCH] updated librejs from 7.20.2 to 7.20.3

User-agent: Gnus/5.13 (Gnus v5.13) Emacs/28.1 (gnu/linux)

Hello,

Please find below a patch updating librejs from 7.20.2 to 7.20.3.  I did
not include the cose signature (/META-INF/cose.sig) and manifest
(/META-INF/cose.manifest), because they are not present in the gnuzilla
source tree.
