internal/chartconfig: consolidate indentation in config.txt

Some of the lines were indented by 2 spaces, some by 4. Make them all
indented by a single tab, and the viewers can use their preferred tab
width in their text editor. This is based on gofmt using a single tab
for indentation (spaces are used for alignment within the rest of the
line, across adjacent lines that are equally indented).

Generating the ./internal/configgen package before and after this has
the same results.
