To much changed file build Flink web page

[Matthias J. Sax-2]

Hi,

I just observed when building the Flink web page locally, that a lot of
files got touched. Even files, that are not related to the actual
change. After asking, it turned out that the problem is different
versions of Jekyll that are used.

I personally think that this is quite annoying and would suggest to
agree on a unique version to be used. What do you think about it?

On my system, version 2.2.0 is installed. Maybe we should use the
version that the majority of people are using right now (to keep the
overhead of changing the version to a minimum). Or is anyone aware of a
technical reason for using (or avoiding) a specific version?
