Update compatibility matrix for fluent bit 1.1.2

Once 1.1.2 release of Couchbase Fluent Bit is out, update the compatibility matrix for it: https://docs.couchbase.com/operator/current/prerequisite-and-setup.html#couchbase-fluent-bit-compatibility

I have a copy of the image here: https://drive.google.com/file/d/1gxEdknddUdJVb8p9fGovI2DAz6Cb9p4U/view?usp=sharing 

You can also use this to carve out the 1.1.2 release in the Couchbase Fluent Bit repo documentation too:

• Releases - new section for main dev and change current section to 1.1.2 release: https://github.com/couchbase/couchbase-fluent-bit#releases
• https://github.com/couchbase/couchbase-fluent-bit#compatibility-matrix-for-cao
