Error while updating from 1.20.x to 1.30.2

[reri42]

Today decided to update to the latest version and ran the update.sh.
The npm ci displayed this message.

For the rest zigbee2mqtt started ok afterwards.

Probably should have updated npm before the update.
Updated from 6.14.13 --> 9.6.2 afterwards.

Ran npm ci again after update and now everything seems ok.

Thought I post this anyway in case it helps someone.
