Currently versions under 13 are EOLed (see [FreeBSD Release Information](https://www.freebsd.org/releases/)). FreeBSD 13 will be EOLed by April 30th (see [Supported FreeBSD releases](https://www.freebsd.org/security/#sup)) while LLVM 23 is expected to be released in August 25th according to the LLVM calendar. Thus assumed that minimum supported FreeBSD version is 14. Signed-off-by: Minsoo Choo <minsoochoo0122@proton.me>
