fix: bump x/tools to 0.30.0 to support Go 1.24

[alexandear]

This PR fixes perfsprint to work with Go 1.24.

How to reproduce

Build perfsprint with Go 1.24, run and get "internal error".

$ go version
go version go1.24.0 darwin/arm64

$ go build -o perfsprint main.go

Expected

$ ./perfsprint ./...
/Users/Oleksandr_Redko/src/github.com/catenacyber/perfsprint/analyzer/analyzer_test.go:60:12: fmt.Sprintf can be replaced with just using the string
/Users/Oleksandr_Redko/src/github.com/catenacyber/perfsprint/analyzer/analyzer_test.go:61:12: fmt.Sprintf can be replaced with just using the string
/Users/Oleksandr_Redko/src/github.com/catenacyber/perfsprint/analyzer/analyzer_test.go:62:12: fmt.Sprint can be replaced with just using the string
...

Actual

$ ./perfsprint ./...
perfsprint: internal error: package "bytes" without types was imported from "github.com/catenacyber/perfsprint/analyzer"
