.github: bump vmactions/freebsd-vm from 1.5.5 to 1.5.6

[dependabot]

Bumps vmactions/freebsd-vm from 1.5.5 to 1.5.6.

Release notes

Sourced from vmactions/freebsd-vm's releases.

v1.5.6

FreeBSD 14.5, and riscv64 can install packages

New releases

FreeBSD 14.5 on x86_64, aarch64, riscv64 and powerpc64. The action now offers 13 releases; the default is still 15.1.

riscv64 gains rsync and sshfs

pkg.FreeBSD.org publishes no riscv64 packages at all, so the riscv64 images used to ship without rsync or fusefs-sshfs and only nfs, scp and tar worked there. Image builder 2.2.7 configures the 15.0 and 15.1 riscv64 images for anyvm-org/freebsd-pkg-repo, a signed build of the ports tree for FreeBSD:15:riscv64, so those two releases now support all five sync methods:

sync: rsync (the default) sync: sshfs sync: nfs sync: scp sync: tar

pkg install also works inside the VM on those images. 13.x and 14.x riscv64 are unchanged and stay on nfs, scp and tar.

Pins

BUILDER_VERSION 2.2.6 -> 2.2.7 ANYVM_VERSION 0.6.5 -> 0.6.9

Fixes from base-vm

• The osname input defaults to lowercase "freebsd".
• rsync keeps its timestamps on this action; the -t workaround added for AlmaLinux/Rocky ppc64le does not apply here.
• scp-mode copyback picks the right archive tool per guest.
