fix(api): Fix openapi documentation display script

[ndv99]

Done

• Fixed OpenAPI display script by replacing "application/json" check in request body with "multipart/form-data"

QA

• Go to /docs/api
• Open a few endpoints that have methods with request bodies
• Ensure there are no duplicate parameters and that the properties are being displayed correctly

A few to check:

• PUT /MAAS/api/2.0/boot-sources/{boot_source_id}/selections/{id}
• DELETE /MAAS/api/2.0/devices/{system_id}/
• DELETE /MAAS/api/2.0/devices/{system_id}/
• PUT /MAAS/api/2.0/dnsresourcerecords/{id}/
