🐛 Bug Report: Functions usage typo

### 👟 Reproduction steps

Go to :
- a project
- your functions
- create one or two functions
- create at least two deployements on one of the function (or both)
- then head on the `Functions` usage (usage tab from the function list, not from a specific function)

### 👍 Expected behavior

According to the title, i should see the number of functions on the graph, but it does not match.

### 👎 Actual Behavior

As shown on the screenshot below, I have 5 functions but it's showing 46.
I think there is a typo and it should be "Total deployments" instead.
Also maybe could be nice to have both :) (deployements and functions usage count)
