cosmetic: trim whitespace in code files

[jf]

trim whitespace specifically from 2 files:

• libs/deps-template/resources/io/github/kit_clj/kit/deps.edn
• libs/kit-generator/src/kit/generator/modules/generator.clj

Note:

• it looks like more can probably be done for libs/deps-template/resources/io/github/kit_clj/kit/deps.edn to tidy things up a bit, but I am just choosing to tackle the whitespace-only line first to make for a better dev experience (when I open up deps.edn in my editor, this line is highlighted and makes me wonder; and I don't think this is unique to my editor (am using Emacs Prelude atm))
• I an choosing to ignore the trailing whitespace in CHANGELOG.md (but feel free to let me know if you want those to be removed as well so I can include it in this PR)
