api: can't filter prefix-list-rules by multiple prefix-list ids or names

[alexonishchenko]

NetBox version
NetBox Community v4.1.11

Describe the bug
When getting prefix-rule-list via api and applying multiple filter expressions like '&prefix_list=X' API responses like a single filter entry is applied (the last one).

To Reproduce
Steps to reproduce the behavior:

1. HTTP GET netbox/api/plugins/bgp/prefix-list-rule/?prefix_list=1&prefix_list=2
2. You will get only prefix-list-rules linked to prefix-list 2.

Expected behavior
Get a list of prefix-list-rules linked to prefix-list 1 and prefix-list 2.

Please re-try with a more recent version of NetBox and the plugin, there's been multiple fixes since that release.
