Urgent Issue: Pokemon search function for Pokemon with multiple Forms

[VGCPastes]

Pokemon search has to factor in the multiple forms of the following species, meaning that the search has to be encompassing for the following species!:

1. Maushold -> If I search Maushold, we must retrieve results for Maushold and Maushold-Four
2. Gastrodon and Gastrodon-East
3. Toxtricity and Toxtricity-Low-Key
4. Palafin and Palafin-Hero
5. Dudunsparce and Dudunsparce-Three-Segment
6. Squawkabilly and Squawkabilly-Blue and Squawkabilly-White and Squawkabilly-Yellow

However, these Pokemon must retrieve seperate results:

1. Tatsugiri vs Tatsugiri-Droopy vs Tatsugiri-Stretchy
2. Oricorio vs Oricorio-Pa'u vs Oricorio-Pom-Pom vs Oricorio-Sensu
3. Lycanroc vs Lycanroc-Midnight vs Lycanroc-Dusk
4. Tauros-Paldea-Aqua vs Tauros-Paldea-Blaze

There are other examples of combined search required for the complete pokedex, or when the DLC comes out:

1. Pumpkaboo
2. Gourgeist
3. Zygarde I might be missing some so we will need to update next time as we go along!

Notes for me:

It turns out to be a challenging problem:

• [x] find those species who has different formes but functionality unchanged
• [x] use cartesian product to make copies of filterValue arrays (e.g. ["Maushold-Four", "abc"] -> [["Maushold", "abc"], ["Maushold-Four", "abc"]])
• [x] make multiselect menu to also keep those different formes (current problem: select "Gastrodon-East" -> "abc": ok; select "abc", then you cannot find "Gastrodon-East" yet "Gastrodon" is still there)
