preCompress:true with wildcard:true doesn't use index file if the path doesn't end in /

Prerequisites

• I have written a descriptive issue title
• I have searched existing issues to ensure the bug has not already been reported

Fastify version

3.27.4

Plugin version

4.5.0

Node.js version

16.13.0

Operating system

Linux

Operating system version (i.e. 20.04, 11.3, 10)

21.04

Description

I expect the index.html.bz file to be served when I request a directory without a trailing slash

I think the solution is to add code in

fastify-static/index.js

Line 175 in 84e66b1

reply.callNotFound()

that uses findIndexFile and re-tries the pumpSendToReply with a new path name

something like

let indexPathname = findIndexFile(pathname, options.root, options.index)
if (!indexPathname) {
       return reply.callNotFound()
}
return pumpSendToReply(
            request,
            reply,
            indexPathname + '.' + getEncodingExtension(encoding),
            rootPath,
            undefined,
            undefined,
            checkedEncodings
          )

Steps to Reproduce

folder structure

public/SiteMap/index.html.bz
public/SiteMap/index.html

Setup plugin with :

  fastify.register(fastifyStatic, {
    root: resolve("public"),
    redirect: false,
    wildcard: true,
    preCompressed: true,
  })

Request

curl http://localhost:8080/SiteMap

(note no trailing slash)

Get a 404 error

Expected Behavior

I expect the public/SiteMap/index.html.bz file to be served for /SiteMap url
