Convert ##^script:has-text to $$script[tag-containts]

[ameshkov]

See how this task was implemented in the browser extension:
AdguardTeam/AdguardBrowserExtension#1452

We should do this on the server-side to avoid messing with the old AdGuard versions that don't understand this type of rules automatically.

Please note, that if the ##^ cannot be converted automatically for some reasons, it should be considered invalid.

no typo?

$$script[tag-containts] vs https://kb.adguard.com/en/general/how-to-create-your-own-ad-filters#tag-content-attribute

Uh, that's my bad! We'll fix it asap
