Brighten yellow and black terminal colors in One themes (#24420)

Closes https://github.com/zed-industries/zed/issues/24419

I made some fine adjustments to the color of the theme with reference
to' Window Terminal' to make it look good. If there is anything
inappropriate in this revision, please also point it out. :)
