Tie up the Database internals section with the v4.4

[NataliaIvakina]

The Database internals section was created in 5.x. This means we don't have anything similar in the v4.4 docs.
Some of the pages can be linked to the Java Reference 4.4 and its section Transaction management.

Looks good. I haven't tried the page aliases. I trust you that they work.

Thanks for the documentation updates.

The preview documentation has now been torn down - reopening this PR will republish it.

I spent a lot of time experimenting with page-aliases for the Store formats page. However, I failed to tie it up to the page Display store information in 4.4. The problem is the following: the page Display store information is located at the same place in 4.4 and 5 versions. When I define the page-aliases attribute to use the 4.4 build (4.4@operations-manual:tool/neo4j-admin/neo4j-admin-store-info.adoc), the version selector doesn't connect this page to the target page (Store formats) because the resource ID, assigned to page-aliases, works in xrefs. Thus, there is no benefit in using the page-aliases attribute. I suggest adding a note directing users to the needed page.
