Use bat for Syntax-Highlighted PKGBUILD Review

[domi413]

Is your feature request related to a problem? Please describe.

I'm always frustrated when reviewing PKGBUILD scripts within yay, as the default method lacks syntax highlighting and proper formatting. This makes it harder to quickly understand and analyze the script's contents.

Describe the solution you'd like

It would be a great enhancement if yay could leverage the bat tool to display PKGBUILD scripts. bat provides syntax highlighting and a more visually appealing output, which would improve readability and make it easier to review scripts for potential issues.
