website: fix empty SA and EN section in 14.1R and earlier relnotes

[vladlen]

Summary

PR 282330 reported that the relnotes for 14.1R, 14.0R,
13.3R, 13.2R, 13.1R, and 13.0R
do not contain entries in the SA and EN sections.

This patch fixes the issue. Since relnotes.adoc is not signed,
it is possible to add information that was omitted during
the release process.

The lists are long; a specially prepared tool was used to read
SA and EN texts and check whether they should appear
in relnotes.adoc in the src repository.
