`^script:has-text` is not converted to AdGuard syntax

[Alex-302]

Related to ##^script:has-text Updated AdGuard $$ syntax: https://adguard.com/kb/general/ad-filtering/create-own-filters/#html-filtering-rules

For example, AdGuard for Windows converts uBO's HTML filtering rule forbes.com##^script:has-text(scriptTag) to AdGuard's forbes.com$$script[tag-content="scriptTag"][max-length="262144"] But conversion is not applied to unblocking rules forbes.com#@#^script:has-text(scriptTag)

This causes the error during compiling filters: Error: Invalid selector: '^script:has-text(responseText)' -- Error: unable to select by '^script' — '^script' is not a valid selector in rule: mail.walla.co.il#@#^script:has-text(responseText)
