Delete rulesets which are all gone from DNS

[cschanaj]

I suspected a number of rulesets having all target gone from DNS: #10516 (comment)

Please refer to gone-from-dns-list.txt

@cschanaj, any idea why your script didn't pick up #10738, #10732, #10729?

@Bisaloo For #10738, #10732 The items from the list only include ruleset which

• Disabled by https-everywhere-checker once only
• Number of occurrence of Could not resolve host: == number of non-wildcard target

The command I use can be modified to match rules failed the fetch test twice and Could not resolve host: == 2 * number of non-wildcard target, but I am afraid that the number of false results is going to be much more significant.

As for #10729, I guess it is because of the improper indentation (with space)

Let's wait for the discussion in #10516 (comment) complete before submitting new deletion PRs.

@cschanaj I merged your recent deletion PRs but from #10516 (comment) it sounds like full-fetch-test should get rid of these rulesets automatically, so you don't need to submit PRs to delete them. What do you think?
