[debugger] Fix reading a byte without checking the version of the Protocol

[thaystg]

Should read this byte only in earlier versions.
This can break features while debugging on ios/android.

This is a side-effect of this PR: #52300

I think we should backport to 6.0 or at least to 6.0maui

Does this affect wasm too? If so, then can we add a test there?
And can you mention how this shows up, in the PR description?

This doesn't affect wasm, because wasm is already using 61 version.
I detected it reading the code! I was helping Ilona and saw this error.
