Remove unneeded type: ignore annotations

[jakobandersen]

mypy seems to have gotten more clever.

if you remove the implicit typing from

https://github.com/michaeljones/breathe/blob/d38542ff6a509f80fa75fdf94a4949cee635925e/breathe/renderer/sphinxrenderer.py#L1864

then mypy can infer the type from https://github.com/michaeljones/breathe/blob/2e160cb5ead7e8be9644372e379e394bfb7a21a3/breathe/renderer/target.py#L10

I also had to do somethings to get the pygments API typing.

--- breathe/filetypes.py
+++ breathe/filetypes.py
- import pygments  # type: ignore
+ from pygments.lexers import get_lexer_for_filename
+ from pygments.util import ClassNotFound


 def get_pygments_alias(filename: str) -> Optional[str]:
     "Find first pygments alias from filename"
     try:
-        lexer_cls = pygments.lexers.get_lexer_for_filename(filename)
-        return lexer_cls.aliases[0]
+        lexer_cls = get_lexer_for_filename(filename)
+        return lexer_cls.aliases[0]  # type: ignore
-    except pygments.util.ClassNotFound:
+    except ClassNotFound:
         return None

and add

types-Pygments

to requirements/development.txt

@2bndy5, there are indeed other typing issues that should be fixed in various places. Locally my mypy also complains about more stuff, but maybe it's because it's an older Python version than in the CI.
For now I'll just make the CI green :-).

Interesting to see! I struggled to understand how to make mypy happy with that.
