Fix Javadoc links on the site

[lewisbirks]

I was having a look over the Jooby documentation on jooby.io and noticed that when linking to methods in the javadoc the links weren't working as expected. For example in the Context section there is a link to the Context#locales() method, the generated link for this is
https://www.javadoc.io/doc/io.jooby/jooby/latest/io.jooby/io/jooby/Context.html#locales--
when it needs to be
https://www.javadoc.io/doc/io.jooby/jooby/latest/io.jooby/io/jooby/Context.html#locales()

I have updated the JavadocProcessor to handle this as well as handling links to jooby javadoc from other artifacts (for example when linking to the netty server implementation in the Worker Executor section)

I've had to introduce another attribute, module, as well for the processor when the maven artifact doesn't line up with the declared module. This is only used in the DB Scheduler section for now but if the documentation was updated to include javadoc links to artifacts such as jooby-awssdk-v[1|2] or jooby-commons-email then it would be used there as well.

Other minor fixes have also been applied where noticed.

Just some questions for when the code is being reviewed 🙂

[lewisbirks]

There are many overloads here, which version is wanted or do we want all of the overloads?

[lewisbirks]

This is what it would look like with all the send overloads taken into account

- javadoc:Context[send, byte[\]]
- javadoc:Context[send, byte[\]...]
- javadoc:Context[send, io.jooby.buffer.DataBuffer]
- javadoc:Context[send, io.jooby.FileDownload]
- javadoc:Context[send, io.jooby.StatusCode]
- javadoc:Context[send, java.io.InputStream]
- javadoc:Context[send, java.lang.String]
- javadoc:Context[send, java.lang.String, java.nio.charset.Charset]
- javadoc:Context[send, java.nio.ByteBuffer]
- javadoc:Context[send, java.nio.ByteBuffer[\]]
- javadoc:Context[send, java.nio.channels.FileChannel]
- javadoc:Context[send, java.nio.channels.ReadableByteChannel]
- javadoc:Context[send, java.nio.file.Path]

@lewisbirks Thank you! Appreciated the time and fixes.

[lewisbirks]

Just had a thought, does this one belong here?

@jknack this is all good to be reviewed now, no further questions from me 🙂
