remove extra space from pki_exclude_cn_from_sans so that flag will function as expected
Today, setting --pki_exclude_cn_from_sans returns an error: unknown flag `pki_exclude_cn_from_sans'
Removing the space from the end of https://gitlab.com/msvechla/vaultbot/-/blob/master/internal/pkg/cli/options.go#L43 will resolve this error.
