ci: re-enable badssl endpoints

[toidiu]

Description of changes:

Enables some endpoints which have re-newed their certs: #3300

Call-outs:

badssl certs seem to expire quite frequently and we have had to remove them from the list. Infact the below endpoints still dont work (expired certs or bad host down it seems). For long term sanity we should come up with a more permanent plan because the certs will expire again on August 15, 2022 and will need to be renewed.

#    {"endpoint": "sha384.badssl.com"},
#    {"endpoint": "sha512.badssl.com"},
#    {"endpoint": "tls-v1-0.badssl.com"},
#    {"endpoint": "tls-v1-1.badssl.com"},
#    {"endpoint": "tls-v1-2.badssl.com"},

since the expiration is August 15, 2022 its not worth the temporary solution if badssl breaks again
