Gunvolt tags

BUR #38788 is pending approval.

create implication azure_striker_gunvolt_1 -> azure_striker_gunvolt
create implication azure_striker_gunvolt_2 -> azure_striker_gunvolt
create implication azure_striker_gunvolt_3 -> azure_striker_gunvolt
create implication gunvolt_records_cychronicle -> azure_striker_gunvolt
create implication mighty_gunvolt -> azure_striker_gunvolt
create implication mighty_gunvolt_burst -> azure_striker_gunvolt
create implication gunvolt_chronicles_luminous_avenger_ix -> azure_striker_gunvolt

Currently the Azure Striker Gunvolt tag is used both as a series tag and as an individual tag for the first game in the series. I tagged some images for the first game as azure_striker_gunvolt_1 (gardening it atm, WIP) as a placeholder, as I would like to rename Azure_striker_gunvolt into gunvolt_(series), but I cannot rename it, because it has too many posts.

Renames are only for tags up to 200 posts. Everything else should be aliased.

Also, shouldn't mighty gunvolt burst imply mighty gunvolt instead? Currently all those posts share these two tags.

technically Mighty Gunvolt Burst is a sequel, so I put it into the gunvolt series instead implying mighty gunvolt and I don't think we need a Mighty Gunvolt series tag.
