[BUG] Using old version of node-fetch causes issues with Node20

[drodil]

Describe the bug.

Using version 2.6.7 for node-fetch might cause socket hang up issues when using Node20. See related issue here: node-fetch/node-fetch#1765

Fix was introduced in 2.6.13 but I recommend updating node-fetch to ^2.7.0

Expected behavior

New version of node-fetch with fix in use
