BUR #134 has been approved by @Penance.

create alias based65_final_mix -> based_mix

"based65 final mix" is one of the many versions included in the based_mix repository.

Just like AOM, which all versions use only one tag, regardless of the version
example:
abyss orange mix 2 -> abyss orange mix
abyss orange mix 3-> abyss orange mix
abyss orange mix 3 A1-> abyss orange mix

I believe that base mix should apply the same logic.
there is no need to create tags for all versions ever and ever.
