Fail2ban: $f2bV_matches on abuseipDB with APIV2 (not V1)

[Skyridr]

Using Fail2ban 0.11.0.3 and trying to set it up with AbuseIPDB using APIv2.

According to some issues, it was already resolved with:

actionban = lgm=$(printf '%%s\n...' "<matches>"); curl --fail --tlsv1.1 --data "key=<abuseipdb_apikey>" --data-urlencode "comment=$lgm" --data "ip=<ip>" --data "category=<abuseipdb_category>" "https://www.abuseipdb.com/report/json"

However, APIV2 is using a different setup:

actionban = curl --fail 'https://api.abuseipdb.com/api/v2/report' \
     -H 'Accept: application/json' \
     -H 'Key: <abuseipdb_apikey>' \
     --data-urlencode 'comment=<matches>' \
     --data-urlencode 'ip=<ip>' \
     --data 'categories=<abuseipdb_category>'

Which also results in $f2bV_matches showing up on the report comments on the abuseipDB website. API v1 is already deprecated, so I think the abuseipdb.conf file needs to be updated using the new api v2 code.

This going to escape-issue (via variable) inside the fail2ban (since 0.10.x)...
Just use double quotation mark " instead:
```diff
- --data-urlencode 'comment='
+ --data-urlencode "comment="

Assumed as much as I just found out about it by doing some digging, thanks!

Will the abuseipdb.conf be updated with the v2 API actionban version though? Seeing v1 is deprecated.

Will the abuseipdb.conf be updated with the v2 API actionban version though?

There is a PR #2302 that covers this. So welcome with testing.
