deps: upgrade golang.org/x/tools to v0.25.0

[high-moctane]

Thank you for this great linter!

This PR upgrades golang.org/x/tools to v0.31.0.

With the older version of golang.org/x/tools, an internal error occurs in Go 1.24.

When running wrapcheck with Go 1.24 using the following code:

package main

import _ "context"

func main() {}

the following internal error is reported:

wrapcheck: internal error: package "context" without types was imported from "github.com/high-moctane/example"

("github.com/high-moctane/example" is a placeholder package name.)

Additionally, since upgrading golang.org/x/tools to v0.31.0 makes it work only with Go 1.23.0 or later, I have updated README.md accordingly.

Hey @high-moctane, thanks for the contribution!

This is quite a bump, and limiting compatibility to Go >=1.23 is pretty significant. I'd aim to support at least a couple of minor versions back if we can get away with it.

Do you know if there's an earlier version of golang.org/x/tools which also support v1.24? If you still have your test repository up, maybe you could cycle through a few versions to see what works, unless there's some documentation existing.

@tomarrell, thank you for your review!

It seems that v0.25.0 is the oldest version that works with go1.24.
I tested it on my local machine.

v0.25.0 is compatible with go version 1.22.0 or higher.

@high-moctane nice, then let's roll with that version. Compatibility with v1.22 is at least a couple of versions prior 👍

[high-moctane]

@tomarrell I have updated to v0.25.0. Could you review it again?

[tomarrell]

Looks good to me, thanks a lot!

Thank you!
