fix: bump golang.org/x/tools to v0.49.0 version for Go 1.27 support

[daniil388]

FIX: #229

Problem

goverter fails under Go 1.27 while parsing code.

Go 1.27 emits type export data in the new pkgbits V3/V4 format (golang/go#78242). golang.org/x/tools v0.31.0 — the version currently pinned in go.mod — cannot read that format, so go/packages hands back packages without type information.

Also, the latest golang.org/x/tools version contains Go 1.25.0 in go.mod, so the version in this package has been bumped, too.

A similar class of problems has been resolved before: #186

Actions

I've run go get -u golang.org/x/tools && go mod tidy
