Update README

[swifty-amay]

A separate PR for the README file.

[swifty-amay]

This is in reference to the change requested in README stated as
"You shouldn't need Python anymore, we've migrated to Kiln. But let's update this bit in a separate PR so if you could remove this section, that would be great (keep the typo though!)"

But using 'swift run' is only generating and giving a static ./site folder, so if python3 is not there then who will serve the folder?

Kiln is only being used for building the folder named ./site as stated in ref. to line 37 in
' docs/Sources/VaporDocs/main'

               ' try await Kiln.build(site, contentDirectory: "docs", outputDirectory: outputDirectory, linkChecking: .error,    
                leafTags: VaporDesignTheme.leafTags) '

So what should I do now?

who will serve the folder?

I think we should tell people to use the Kiln CLI, right @0xTim?

[swifty-amay]

Ya you're right
the 'swift run kiln serve' command is working fine
Let me just update it.

Thanks for sharing the info @fpseverino
