Make isOtaCapable static

[pennam]

isOtaCapable() can be a static method and changing to static makes possible to call it directly from ArduinoIoTCloud like this:

https://github.com/pennam/ArduinoIoTCloud/blob/d0346cbd88fbb81240eef419ea1dfba7fccee9f6/src/ArduinoIoTCloudTCP.cpp#L209

LGTM 👍 (I also had to check the actual code, as the PR only shows the header, but since no member variables are modified, its fine to make it static 👍 )

LGTM +1 (I also had to check the actual code, as the PR only shows the header, but since no member variables are modified, its fine to make it static +1 )

👍 👍 Thanks 😉
