This is a manual backport of #153878 to 3.13.
The automated backport (#154126) fails the docs build. That PR removes Doc/library/lzma.rst from the nitpick ignore list, but on 3.13 six of the BCJ filter references in that file are still unresolved and now show up as warnings: FILTER_X86, FILTER_IA64, FILTER_ARM, FILTER_ARMTHUMB, FILTER_POWERPC and FILTER_SPARC.
On main those names are written with a leading !, which tells Sphinx to render them as plain text without looking for a reference target. That prefix was added by the change that introduced the ARM64 and RISCV filters (GH-115989), which was never backported, so the release branches still carry the plain references.
This backport adds the same ! prefix to those six lines, so the file builds cleanly under nitpicky mode and renders the same way it does on main. I checked with a nitpicky docs build that lzma.rst produces no warnings.
Supersedes #154126.
Sorry, something went wrong.

…st` (pythonGH-153878)
The lzma module constants (FORMAT_*, CHECK_*, PRESET_*, FILTER_*, MODE_*
and MF_*) were referenced with the :const: role throughout the module
documentation but were never defined as reference targets, producing
"reference target not found" warnings under nitpicky mode.
Document these public constants with .. data:: directives, following the
convention used by the signal, socket and ssl modules, so the existing
references resolve. The now-redundant inline descriptions of the format
and check constants are condensed into linked references.
(cherry picked from commit 1530b38)
