feat: replace monitorJSON.name with monitorJSON.pathName to display the monitors path, not just the root

[SOwOphie]

As noted in #3798, it would be great to have the alarm notification include the full monitor path. This was done for Mattermost in #3801, but not for all the other notification providers. This commit replaces all other trivial occurences of monitorJSON.name with monitorJSON.pathName.

I only really care about the Discord notification providers, but I also changed all the other low hanging fruits I could find. Only Discord is personally tested by me as I do not have access to the other providers. If you consider this too sketchy to merge, I will gladly drop the changes to the other providers.

@SOwOphie Short headsup: @II-EMC noticed in #5760 that pathName does not contain the name anymore. Could you have a look if this affects your change as well?

Not shure what caused this regression or if this was intentional.

Due to personal health issues, I see myself unable to deal with this in a reasonable time frame. If anybody else wants to take this up, please be my guest. Sorry for wasting your time.
