Hi, Since you mentioned Starplot in matplotlib/matplotlib#30960, figured you might be interested in identifying the project as an mpl downstream library on PyPI via the trove classifier. Also please consider your very cool library to https://matplotlib.org/thirdpartypackages/

Thanks for the PR! What happens if someone passes in a string fontweight (for example they're saving to multiple filetypes)? |

PR summary
This fixes a small bug with handling integer font weights when rendering text in SVGs as elements vs paths (i.e. plt.rcParams['svg.fonttype'] = 'none').
To reproduce:
Raises:
The problem is that the font weight_dict is keyed on the string values, but get_weight returns an integer.
PR checklist
I couldn't find an open issue for this, but let me know if one exists already. This is also my first PR to matplotlib, so let me know if there's anything I missed in your contribution process. Appreciate any feedback! And, thanks so much for maintaining this library! It's the backbone of Starplot, a sky mapping library I maintain.
