Log Message:
py-sphinxcontrib-bibtex: updated to 2.6.2

2.6.2 (10 January 2023)
-----------------------

* Fix bibliography header repetition when recompiling documents

2.6.1 (27 August 2023)
----------------------

* The ``:cite:alp:`` role in the super style now also suppresses the sup tag
  in addition to the brackets, to make it easier to apply the necessary formatting
  around the citation.

2.6.0 (24 August 2023)
----------------------

* Pre- and post-text in citations are now supported for the
  author_year, label, and super referencing styles. The syntax is
  ``:cite:p:`{pre-text}key{post-text}```
  Refer to the documentation for more details.

* New alternative style citations are now supported for the
  author_year, label, and super parenthetical referencing styles,
  which are identical to parenthetical citations but without the brackets.
  The syntax is ``:cite:alp:`key```.
  Refer to the documentation for more details.

* Exclude docutils 0.18 and 0.19 to fix generation of a spurious div tag in the
  html builder.

* Add test for running the extension on Cython modules.

* Add test for running the extension with autoapi.

* Sphinx versions 2.x (and lower) are no longer supported.
  New minimum required version of Sphinx is 3.5.

* Running pytest without arguments will now by default skip all marked tests
  that require additional dependencies (currently numpydoc, rinohtype, and
  cython).

* Fix encoding issues when running tests on Windows.

* Python 3.6 is EOL and is therefore no longer officially supported.
