Allowing plugin to work with vite 5

[guruyaya]

This plugin works well with version 5 of vite. These changes will open this plugin to new users

This plugin is very useful and has proven the test of time. I can confirm this plugin to work with vite@5.4.11.

I forked this because I needed to update the project for vite 6 and this doesn't seem to be maintained anymore: https://github.com/awenovations/vite-plugin-replace

Available npm package here: @awenovations/vite-plugin-replace

@deleonio I don't mind taking over ownership of this repo, I find it very useful also and I'll be maintaining it either way

I can meege and publish that sorry
