Some translations fail in v.1.0.0

[mcjulian1107]

Describe the bug

Some translations are not implemented correctly due to the last update:

"repository" was changed to "Repository" "suggest edit" was changed to "Suggest edit" "open issue" was changed to "Open issue" and added "Show source"

I don't know if something is missing

Reproduce the bug

load the theme with another language for example "language = 'es'

List your environment

sphinx-book-theme==1.0.0
