Decreases blood bag IV insertion time (#3950)

# About the pull request

This PR makes it take 1 second instead of 3 seconds (times the surgery
skill multiplier) for blood bag insertion time.

# Explain why it's good for the game

This is taking too long which is severely disincentivizing usage of a
mechanic we want to encourage.
