Whitespace required around != operator

[jszwedko]

The following:

 .ddtags.kube_namespace=="kong" &&  .message!="[notice] 2383#0:4 [lua] init.lua:272:"

Gives the error:

error[E203]: syntax error
  ┌─ :1:38
  │
1 │  .ddtags.kube_namespace=="kong" &&  .message!="[notice] 2383#0:4 [lua] init.lua:272:"
  │                                      ^^^^^^^

Adding whitespace around the != seems to fix it:

 .ddtags.kube_namespace=="kong" &&  .message != "[notice] 2383#0:4 [lua] init.lua:272:"
