Account for upcoming change in WP 5.7 / script tag use

PR https://github.com/WordPress/WordPress-Coding-Standards/pull/1956 in WPCS refers to changes in WP Core which will remove the use of the `` HTML tag in PHP code.

Any existing sniff which looks at the content of inline HTML and takes the `<script>` tag into account will need to be reviewed to see if it can still detect what it is looking for with the "new" way of writing this type of code.

This PR to WP Core gives some good examples of the "new" way of writing this type of code and can be used to for code samples: https://github.com/WordPress/wordpress-develop/pull/498/files

This PR shows the new functionality which will be added to Core: https://github.com/WordPress/wordpress-develop/pull/591

审查现有的、用于检查内联 HTML 中 script 标签的 sniffs，以链接的 WPCS 和 WordPress Core PRs 作为起始参考和代码示例。检查 WP 5.7 变更后它们是否仍能检测相关模式；完成的标准是受影响的 sniffs 能正确处理新样式。
