Some tox targets need better escaping on macOS

Describe your environment

OS: macOS Sonoma

What happened?

The tox targets tracecontext and getting-started use escaping that doesn't appear to work on macOS.

e.g.:

(.venv) user@C02CT31XMD6R opentelemetry-python % tox -e tracecontext

Steps to Reproduce

Run run tox with the tracecontext target on a mac: % tox -e tracecontext

Expected Result

Tests execute.

Actual Result

ERROR: InvocationError for command /Users/user/open-telemetry/opentelemetry-python/.tox/tracecontext/bin/pip install -e opentelemetry-api -e opentelemetry-semantic-conventions -e opentelemetry-sdk -e 'git+https://github.com/open-telemetry/opentelemetry-python-contrib.git@main\' (exited with code 1)

Notice the trailing backslash above (main\)

Additional context

On macOS a solution is to remove the backslashes in front of the pound symbols \# in tox.ini and instead wrap the problematic arguments in quotes.

e.g. replace arguments such as {env:CONTRIB_REPO}\#egg=opentelemetry-util-http&subdirectory=util/opentelemetry-util-http with "{env:CONTRIB_REPO}#egg=opentelemetry-util-http&subdirectory=util/opentelemetry-util-http"

There's a similar issue in contrib.

Would you like to implement a fix?
