docs: remove pull statistics from README

[MikeMcC399]

• closes Incorrect label for pull stats #1393

Situation

In the table at the top of the README document, the column "Monthly pulls" is incorrectly labeled as "Monthly". It's the total since first publication:

---

The Cypress organization on Docker Hub shows the equivalent pull figures as the total number of pulls over all time, not a monthly figure.

---

Cypress Docker images are now in a mature phase of their life cycle and there is no sign that the presentation of download statistics has any influence on user's download choices.

Additionally, the picture is incomplete, since the statistics only refer to:

• Docker Hub and not to
• Amazon ECR (Elastic Container Registry) Public Gallery pulls

In summary, the statistics are incorrectly presented and there is no value to display them in the README.

Change

Remove the column "Monthly pulls" from the README document.
