Remove Log.Trace as it is not exposed on the Extism CLI

[hilaryRope]

This issue is made of two parts:

• Amend The go-pdk documentation at this line: https://github.com/extism/go-pdk/blob/de6b7b8bb649f16ed1d48b957e10986fa7fb86a7/README.md?plain=1#L196 as it should read "A warn log!"
• Remove LogTrace as it does not seem to be exposed on the Extism CLI side and does not come up even if the log level is set to --log-level=trace. Here is an example:

//export log_stuff
func logStuff() int32 {
    pdk.Log(pdk.LogInfo, "An info log!")
    pdk.Log(pdk.LogDebug, "A debug log!")
    pdk.Log(pdk.LogWarn, "A warn log!")
    pdk.Log(pdk.LogError, "An error log!")
    pdk.Log(pdk.LogTrace, "A trace log!")
    return 0
}

func main() {}

Compile it onto .wasm:

tinygo build -o plugin.wasm -target wasi main.go

and finally:

extism call plugin.wasm log_stuff --wasi --log-level=trace

2024/07/12 23:48:44 A debug log!
2024/07/12 23:48:44 A warn log!
2024/07/12 23:48:44 An error log!

Happy to pick this up and resolve it. Long term solution should be to update every SDK and PDK to support trace. There will be a separate ticket for it

I will pick this up :)
