rfctr(ppt): remove double-decoration (#3701)

Somehow this slipped through the earlier PR removing double-decoration
from PPTX.

Remove the decorators from PPT (because it is a delegating partitioner)
and let the decorators on the proxy partitioner (`partition_pptx()`) do
the needful.

@@ -13,10 +13,11 @@
 * **Fix occasional `KeyError` when mapping parent ids to hash ids.** Occasionally the input elements into `assign_and_map_hash_ids` can contain duplicated element instances, which lead to error when mapping parent id.
 * **Allow empty text files.** Fixes an issue where text files with only white space would fail to be partitioned.
 * **Remove double-decoration for CSV, DOC, ODT partitioners.** Refactor these partitioners to use the new `@apply_metadata()` decorator and only decorate the principal partitioner (CSV and DOCX in this case); remove decoration from delegating partitioners.
-* **Remove double-decoration for PPT, PPTX, TSV, XLSX, and XML partitioners.** Refactor these partitioners to use the new `@apply_metadata()` decorator and only decorate the principal partitioner; remove decoration from delegating partitioners.
+* **Remove double-decoration for PPTX, TSV, XLSX, and XML partitioners.** Refactor these partitioners to use the new `@apply_metadata()` decorator and only decorate the principal partitioner; remove decoration from delegating partitioners.
 * **Remove double-decoration for HTML, EPUB, MD, ORG, RST, and RTF partitioners.** Refactor these partitioners to use the new `@apply_metadata()` decorator and only decorate the principal partitioner (HTML in this case); remove decoration from delegating partitioners.
 * **Remove obsolete min_partition/max_partition args from TXT and EML.** The legacy `min_partition` and `max_partition` parameters were an initial rough implementation of chunking but now interfere with chunking and are unused. Remove those parameters from `partition_text()` and `partition_email()`.
 * **Remove double-decoration on EML and MSG.** Refactor these partitioners to rely on the new `@apply_metadata()` decorator operating on partitioners they delegate to (TXT, HTML, and all others for attachments) and remove direct decoration from EML and MSG.
+* **Remove double-decoration for PPT.** Remove decorators from the delegating PPT partitioner.
