The dependabot PR #2765 ran into compatibility issue, needs manual upgrade

Describe the bug

make vendor-check fails when the path has spaces, for example /Users/username/Path With Spaces/work/savishy-tempo.
The error is docker: invalid reference format. which I have seen typically when Docker thinks we are passing it incorrect arguments.
I moved to a path without spaces i.e. /Users/username/savishy-tempo and make vendor-check works fine.
My first gue

After the merge of this PR: open-telemetry/opentelemetry-dotnet#1548

We should create more unit tests just like open-telemetry/opentelemetry-dotnet#1537 to validate the full behavior.

Another use case:
It would be nice to just attach files with

@thegryfon noticed that in community axios implementations, some leak contexts and you wouldn't necessarily know until a second root trace is attempted.

here's an example scenario I think tests could cover:

there is no parent trace in scope
create a client request
create a second client request
verify that both client requests are root spans

Cannot use same trace ID accross different node of microservices
