Add .replace to omit commas in the array of case IDs

[asalgado87]

Commas are being included in some of the case ID strings, causing a 400 response from testrail. I've tested this change on my machine and this fixes the issue.

hi
thank you so much for this
do you know whey they are added? do you have a sample test-description where that happens?
is this then a bug in the extractor of case ids?

[asalgado87]

I actually found that someone in our org had included commas separating test case ids.
example: 'C1234, C1235, C1236: test case example title'

So it turns out there was an issue with mapping on our side, not an actual bug.
This change will provide a guardrail in such a case but isn't totally necessary.
I found this out after putting up the pr so apologies for the unnecessary noise.
