removed 'apple-' prefix from all <meta> instances

Fixes #1269

Deprecated app-mobile-web-app-capable meta tag replaced with mobile-web-app-capable.

@bobisjan is there anything I can do to help get this merged and released?

Sorry for the delay 😞, I'll take a look during this week 👀

[bobisjan]

What is the purpose of the new meta tag? I could not find any relevant information, I recall that original meta tag (apple prefixed) was used in mobile Safari years ago, but it was basically replaced by Web App Manifest <link rel="manifest" href="manifest.json">?

My recommendation would be to disable meta tag via webAppCapable: false, and use manifest. What do you think?

@bobisjan Sorry it took so long to respond to this! One thing I found that is somewhat recent is this web.dev article: https://web.dev/learn/html/metadata#other_useful_meta_information. Oddly enough, they recommend using both tags, so now I'm not sure if this PR is even useful -_-
