chore(exporter): fix lint warnings

[alisabzevari]

related to #1093

Which problem is this PR solving?

• This PR fixes lint warnings in exporter-prometheus and exporter-zipkin packages.

Short description of the changes

• Fix lint warnings
• The warnings regarding the deprecation of url.parse haven't been fixed because they need more manual work. I will tackle them in a different PR if needed.
• I have renamed statusCodeTagName and statusDescriptionTagName exported variables to fix the name shadowing issue in transform.ts, but I am not sure this doesn't have any side effects. Let me know if I should revert them.
