[bug#49280] [PATCH v2 1/3] gnu: racket: Update to 8.2.

[Philip McGrath <philip@philipmcgrath.com>]

* gnu/packages/racket.scm (racket-minimal, racket): Update to 8.2.
* gnu/packages/racket.scm (racket-minimal)[#:arguments]: Fix
patch-config.rktd-lib-search-dirs phase. When a config.rktd file
doesn't contain an entry for `lib-search-dirs`, the default is
equivalent to `'(#f)`, not `'()`.
