Fix failing pipeline

The latest build failed for multiple reasons:

• Insufficient storage space
• Runner timed out
• Pipe between wget and tar command causing build to stall

This MR does the following to fix this issue:

• Bump the runner size to saas-linux-medium-amd64
• Increase wget timeout
• Remove pipe between wget and tar

At the same time, I've also increased this project's job timeout to 2 hours.
