Add new linters to README.md; remove LazyData from DESCRIPTION

[AshesITR]

fixes #825 and #827

[MichaelChirico]

recommend adding a note to do this before release in a document in .dev/

[AshesITR]

Nice idea. Looking at the source code of usethis::use_release_issue() it seems one can define a function release_bullets within the package to automagically add it to the auto-generated issue.

use_release_issue() will include additional bullets if your package includes release_bullets() function which returns a character vector (and the package has been loaded with load_all()) (r-lib/usethis#941).

I #nocov'd the function but locally tested.

You can try

devtools::load_all()
usethis:::release_checklist("3.0.0", TRUE)
