kernel name is missing a dash when setting custom_pkgbase to something with "tkg"

[z0n]

OS: Arch
Kernel: 6.10.2

When setting the _custom_pkgbase to something with tkg, e.g. linux-tkg, the kernel name will be 6.10.2-273linux-tkg instead of 6.10.2-273-linux-tkg.
Here's where it happens in the prepare script:

linux-tkg/linux-tkg-config/prepare

Lines 655 to 658 in 2716916

	if [[ "$_custom_pkgbase" != *tkg* ]]; then
	_localversion_tag="-tkg-"
	fi
	echo "-${pkgrel}${_localversion_tag}${_custom_pkgbase}" > localversion.10-pkgrel

Note that there'll be no - between the ${pkgrel} and ${_custom_pkgbase} if $_custom_pkgbase includes tkg.

Don't have time to create a fix PR, sorry 😅 Should be easy to fix though!
