Neovim auto updates

[TomJo2000]

• closes Auto update failing for neovim #28188
• closes Auto update failing for neovim-nightly #28102

I haven't been able to work out any reason for why neovim and neovim-nightly incorrectly calculated their checksums wrong the last time they tried to auto-update.

The neovim auto-updates succeed locally on my machine.
I traced the error message back to this block.

termux-packages/scripts/updates/utils/termux_pkg_upgrade_version.sh

Lines 142 to 146 in 6606080

	if ! "${TERMUX_SCRIPTDIR}/scripts/run-docker.sh" ./build-package.sh -C -a "${TERMUX_ARCH}" -i "${TERMUX_PKG_NAME}"; then
	_termux_should_cleanup "${big_package}" && "${TERMUX_SCRIPTDIR}/scripts/run-docker.sh" ./clean.sh
	git checkout -- "${TERMUX_SCRIPTDIR}"
	termux_error_exit "failed to build."
	fi

Which doesn't help make things clearer.

• This could be a regression introduced by chore(scripts/update-checksum): make sure $repo always has a value #27466, but since I am unable to replicate the failure locally there's no way to be sure.
