fix: add qoutation marks around bash variables

[FatumaA]

Added quotation marks around variables.
Builds but leaves lots of warnings:
Edit: The warnings were not there before I added the quotes

those issues are probably unrelated.

@chalin PTAL, I think that looks good, but since you wrote most of the script I would like to get your review as well

Hi @FatumaA. Thanks for this attempt at a fix, but this breaks the build rather than fixing it. As you've noted already, the warnings (which are a symptom of the build not working), were not there before. https://github.com/open-telemetry/opentelemetry.io/actions/runs/11372802351/job/31638107804?pr=5377

Let me take a look at a fix and report back here.
