List more terminals supporting overline

[Jared Finder]

Looking at https://invisible-island.net/ncurses/terminfo.src.html, I 
think more terminals could list support for Smol and Rmol to toggle 
overline mode.  I have tested locally that the following terminals 
support overline and are not listed as such:

Windows Terminal (ms-terminal)
Konsole (konsole)
iTerm2 (iterm2)
They all use the same \E[53m and \E[55m that Contour and WezTerm use.

Can the database be updated?
