InfluxDB Docker image 2.3 has 60% size increase

There is a surprising growth for only minor changes in the shipped software:

1. [2.2-alpine](https://hub.docker.com/layers/influxdb/library/influxdb/2.2-alpine/images/sha256-1da5bab4a554d5f2741940acee82d07519e783379487a4f36a7e31cfe2d4b22a?context=explore) **120 MB**
2. [2.3-alpine](https://hub.docker.com/layers/influxdb/library/influxdb/2.3-alpine/images/sha256-1d36b2bf6393349521f556ca7e9e40a17b9814a9e65913fb9113174d3a2bf7ea?context=explore) **190 MB**

Is there a legitimate cause for it or maybe an oversight and a considerably smaller 2.3 image could be produced?

Start by comparing the linked 2.2-alpine and 2.3-alpine Docker image layers to identify what accounts for the size increase. Inspect the image build configuration after locating the relevant change; done means either reducing the unnecessary size increase or documenting a legitimate cause for the larger image.
