Go 1.21 sprecified in readme, although 1.24 is needed

[dkgitdev]

First, thanks for this awesome project I use for my personal backups every month!

Describe the bug
Hi! I'm trying to build the package while making a Homebrew Formulae.
It states that go 1.24 is needed, although readme states it requires 1.21.

To Reproduce
Follow the build instructions from the readme: go build .

Expected behavior
A clear and concise description of what you expected to happen.

==> go build .
go: ../../go.mod requires go >= 1.24.0 (running go 1.21.13; GOTOOLCHAIN=local)

Additional context
I suppose you just have to update the readme, if move onto go 1.24 was intentional
