Fix typo in OpenTelemetry

[MA3CIN]

Which problem is this PR solving?

a typo in troubleshooting.MD

Surprisingly, the spellcheck didn't pick this one up, probably due to the Markdown hashtags being interpreted as a comment.

I recall there were many misspelled words added to the dictionary file, can you check?

[MA3CIN]

@yurishkuro Yes, you are right. Some of these are an easy fix, but the rest... I'm not sure if these are even words in English...?
boths? bohara? afzal? ansh? Most of these are names. I guess if a word is neither a name nor an established term in Software, i'll purge it.

[yurishkuro]

boths? bohara? afzal? ansh?

boths sounds like a typo, the others are people's names (interns from the mentorship program / page). I don't know what a good way to handle this, we cannot just remove them from the dictionary, the linter will start failing.

[MA3CIN]

@yurishkuro Alright, then i propose the following:
Accept and close this PR, because the changes here are indifferent to the linter and spellchecker
I'll open a separate PR fixing the Dictionary file, on which we can review and discuss the proposed changes

[yurishkuro]

Sure, but to complete this PR I want to make sure this misspelled work is not in the dictionary.

[MA3CIN]

@yurishkuro I see - all three (opentelemetry, opentracing, openzipkin) are spelled correctly in the dictionary. I checked that initially, but didn't comment that I did. The spellechecker must have ignored Markdown hashtags, and interpreted them as a comment.
