Bowtie colour implication

BUR #26865 has been approved by @nonamethanks.

create implication multicolored_bowtie -> multicolored_bow
create implication multicolored_bowtie -> bowtie
create implication two-tone_bowtie -> two-tone_bow
create implication two-tone_bowtie -> bowtie
create implication gradient_bowtie -> gradient_bow
create implication gradient_bowtie -> bowtie
create implication gradient_bow -> bow

Sequel of topic #21731. I think multicolored_* should be used for items having more than 2 colours.

These multicolored/two-tone tags are starting to overstay their welcome TBH, they form a weird tree of implications where a two-tone bowtie should be tagged with tons of downstream tags: two-tone bowtie + yellow bowtie + green bowtie -> bowtie + two-tone bow + yellow bow + green bow -> bow... And I'm sure gradient bowtie and two-tone bowtie are also getting multicolored bowtie on them.
