Increase CPU limit for webservice in review-apps

What does this MR do and why?

If you try the following search query in Slack:

in:#review-apps-monitoring container_name=webservice ongoing

You will see that we've had a few alerts for the webservice container CPU limit:

Most of them are very small values:

1.000 with a value of 1.010
1.000 with a value of 1.011
1.000 with a value of 1.028
1.000 with a value of 1.020

This MR increases the CPU limit a bit, so that we get rid of those alerts.

Screenshots or screen recordings
