Docs: Make text in code blocks searchable

[VictorIreri]

Searching for text present only in code blocks yields no results.
For example, "uncompletedTestRetryQuota" can't be found because, throughout the docs, it's only present in a code block. I would expect all displayed text in the docs to be searchable.

There was an issue in docasaurus and docsearch: facebook/docusaurus#3172
Although docsearch can index code samples, they do not recommend it: https://docsearch.algolia.com/docs/docsearch-program/#can-you-index-code-samples

So, I guess it would be better not to enable searching in code samples, but rather put important parameters out of code blocks in docs
