feat: Add option to exclude pages

[JosuaMeier]

Would be nice to have the option to exclude pages from output file.

@JosuaMeier hiya, another fellow plugin user here. Although adding it here would be nice, but i figured out the same result by using patterns in vuepress config:

  patterns: process.env.EXPORT_PDF === 'True' ? ['**/*.md', '**/*.vue', '!**/openapi.md', "!*/index.md", "!index.md"] :  ['**/*.md', '**/*.vue'],

@aporan Thx for your response.

If I use the your pattern snippet, its not working. process.env.EXPORT_PDF is undefined. Where do I have to provide this variable.
If it is as easy as you mentioned, I would surely prefer your solution.

Sorry, I am very new on the VuePress topic. (1 day) 🙈

Hi, It's just an environment variable I'm defining in cli. You ca remove that and use the first array. Ofcourse, depending on your use case, you've to tweak the file types. Mine won't work directly. The second array in the ternary operator is the default value vuepress uses.

@aporan Yeah, works perfectly. No need for this pull request. Thank you.

Hi, thanks for this contribution!
I'll open this PR to keep in mind to add this feature, because I need it too.
Currently, since I'm building sidebar links programmatically, I'm filtering pages here, so including it into the plugin itself will be nicer.

FYI, I didn't really want to have to create an env. variable so i did this instead:

patterns: process.argv.includes("export") ? ["**/api/**/*.md", '**/*.vue'] : ['**/*.md', '**/*.vue']
