Wrong value for SHA256 in docs

[mikem23]

Both format_v4.md and format_v6.md have

SHA256              |  272  | STRING

However, it appears the actual value is 273, as listed in tags.md. The code says RPMTAG_SIG_BASE+17, which works out to 273.

... unless I'm missing something?

Oops, indeed. Thanks for spotting and reporting!
