Unhyphenate and alias P-chan (P90)

BUR #17504 has been approved by @nonamethanks.

create alias p-chan_(p-90) -> p-chan_(p90)

Why is this weapon name tag hyphenated despite the official designation of the FN P90 is written without it? That's weird.
Requested this for standardized consistency and searchability. Implication is based on the Wiki.

The bulk update request #17504 (forum #244377) has been approved by @nonamethanks.

For the record, some 'official' (I think) material include the hyphen in the gun's name: this image and this tweet from an airsoft company.
