libsosplugin cannot be loaded into lldb (macos arm64)

### Description

I try to install dotnet-sos to get an ability to debug dotnet programs on mac, but after installing it according to [this manual](https://github.com/dotnet/diagnostics/blob/main/documentation/building/osx-instructions.md), lldb shows error on startup:
```
$ lldb
error: this file does not represent a loadable dylib
error: 'setsymbolserver' is not a valid command.
(lldb)
```

Futher context:
```
$ cat .lldbinit
#START - ADDED BY SOS INSTALLER
plugin load /Users/yuraaka/.dotnet/sos/libsosplugin.dylib
setsymbolserver -ms
#END - ADDED BY SOS INSTALLER
```

Also, I tried to build libsosplugin [from source](https://github.com/dotnet/diagnostics), but got the same result.
What do I do wrong?
