Update Never Cache Cookies textarea description to explain partial matches are allowed

[alfonso100]

Is your feature request related to a problem? Please describe.
Our Never Cache Cookies exclusion box accepts a partial match, so adding wp_woocommerce_session_ will also exclude any cookie including that string on its name, like in the case of tokenized cookies, ie: wp_woocommerce_session_[TOKEN]

This is not clearly documented and it might lead users to understand the cookie match has to be literal.

Describe the solution you'd like

• Update the field description to let users know that a partial match is allowed: "Partial matches are allowed"
• Create a DOC about Never Cache Cookies, explaining its usage, documenting the possibility of using partial matches. and linked from UI like in other exclusion boxes with the "More Info" links: https://jmp.sh/ZcUiRfo

Additional context
On this doc we already recommend the usage of a partial match to exclude yith_wcwl_session_ type cookies.

On this issue: #1358 we are requesting the usage of wildcards, and it could lead users to think that any cookie exclusion has to be literal.

Suggested update to the help text (#3334 (comment)): Specify full or partial IDs of cookies that, when set in the visitor's browser, should prevent a page from getting cached (one per line). More info

@webtrainingwheels What do you think? Also, do you think creating a doc is feasible for this?

@arunbasillal Looks good! And yes, we can do a doc!
