Review changelog to improve formatting

[selul]

Changelog has a few entries which is acting strange https://vertis.d.pr/i/8ARLxC, we can look into fixing the parsing or list the content as it is without tabs and such.

@girishpanchal30 I dont think this is enough, we need either to fix the parsing to be consistent or display changelog as it is without any tabs and anything.

The thing with edits on the changelog is that it can always come back when a new version is using some strange chars/format.
