Subject: [PATCH] Documentation: process: Do not hardcode kernel major version number

The big picture section of 2.Process.rst currently hardcodes major
version number to 5 since fb0e0ffe7fc8e0 ("Documentation: bring process
docs up to date"). As it can get outdated when it is actually
incremented (the recent is 6 and will be 7 in the near future), replace
it with the placeholder.

Note that the version number examples are kept to illustrate the
numbering scheme.
