CurseForge mod downloads fail when .download.url is present in .pw.toml file but contains an empty string

[LadyAelita]

For example, the following works:

filename = 'betterfpsdist-1.19.2-4.1.jar'
name = 'betterfpsdist mod'
side = 'both'

[download]
hash = '0dc6528d4e9208221485bc8fa6e0e5fdf427364e'
hash-format = 'sha1'
mode = 'metadata:curseforge'

[update.curseforge]
file-id = 5100224
project-id = 551520

But this produces an error:

filename = 'betterfpsdist-1.19.2-4.1.jar'
name = 'betterfpsdist mod'
side = 'both'

[download]
hash = '0dc6528d4e9208221485bc8fa6e0e5fdf427364e'
hash-format = 'sha1'
mode = 'metadata:curseforge'
url = ''

[update.curseforge]
file-id = 5100224
project-id = 551520

I would like it if Packwiz Installer skipped .download.url if it's equal to "", treating it as if it was null/undefined. Prism Launcher generates CurseForge metadata files with url = '', and it would be super inconvenient to have to pre-process all those files and drop the url = '' lines.
