Subject: bs4: Update to 4.12.3 from 4.4.1

It makes sense to switch to a more recent version and keep up to date
with upstream changes and things like new python version support.

(Bitbake rev: f5462156036e71911c66d07dbf3303cde862785b)

+    """Describes a strategy to use when outputting a parse tree to a string.
+
+    Some parts of this strategy come from the distinction between
+    HTML4, HTML5, and XML. Others are configurable by the user.
+
+    Formatters are passed in as the `formatter` argument to methods
+    like `PageElement.encode`. Most people won't need to think about
+    formatters, and most people who need to think about them can pass
+    in one of these predefined strings as `formatter` rather than
+    making a new Formatter object:
+
+    For HTML documents:
+     * 'html' - HTML entity substitution for generic HTML documents. (default)
+     * 'html5' - HTML entity substitution for HTML5 documents, as
+                 well as some optimizations in the way tags are rendered.
+     * 'minimal' - Only make the substitutions necessary to guarantee
+                   valid HTML.
+     * None - Do not perform any substitution. This will be faster
+              but may result in invalid markup.
+
+    For XML documents:
+     * 'html' - Entity substitution for XHTML documents.
+     * 'minimal' - Only make the substitutions necessary to guarantee
+                   valid XML. (default)
+     * None - Do not perform any substitution. This will be faster
+              but may result in invalid markup.

+        :param cdata_containing_tags: The list of tags that are defined
+           as containing CDATA in this dialect. For example, in HTML,
