corrects explnation of default max_lifetime values in README.md

[oakgary]

The current version of the README states:

Note that max_lifetime = 60 * (30 + Math.random() * 30) by default. This resolves to an interval between 45 and 90 minutes to optimize for the benefits of prepared statements and working nicely with Linux's OOM killer.

The range of 60 * (30 + Math.random() * 30) is 1800-3600, therefore 30 to 60 minutes.

Both versions define the max_lifetime as 60 * (30 + Math.random() * 30)
