Like Neato remove certificate for Vorwerk

[Najihel]

Hello,

At the moment https://github.com/stianaske/pybotvac/blob/master/pybotvac/cert/ksecosys.com.crt is an old certificate :

Serial Number=0F 91 EA 32 C5 00 E8 1C 29 BF 1C 5E 34 20 24 7F
Not Valid Before=Thursday 7 July 2022 at 02:00:00 Central European Summer Time
Not Valid After=Saturday 8 July 2023 at 01:59:59 Central European Summer Time

The production one is

b1:24:bf:bc:02:5b:2f:1c:a6:b8:a3:2d:68:3c:de:0f
            Not Before: May  6 00:00:00 2024 GMT
            Not After : May  6 23:59:59 2025 GMT

Maybe like Neato through #89 it's possible to remove locally stored wildcard certificate of *.ksecosys.com

I think some PR and issues are related to :

• Plugin after OpenSSL Update down nicoh88/homebridge-vorwerk#18
• remove manual cert validation for vorwerk connections #83
• https://community.home-assistant.io/t/creation-of-vorwerk-kobold-component/253166/92

Thanks
