chore: add ja3Hash to request.cf.botManagement

[KianNH]

Closes #213

Example: https://kian.org.uk/cf.json

"botManagement": {
  "ja3Hash": "2a18e6bf307f97c5e27f0ab407dc65db",
  "staticResource": false,
  "verifiedBot": false,
  "score": 98
},

It doesn't appear on all zones with Bot Management, i.e https://workers.cloudflare.com/cf.json, so adding as optional.

Hey there! Thanks a lot for @KianNH this PR and @mrbbot for merging it!

Is there a release planned that would ship this change? Thanks!

[KianNH]

Also raised #275 for the new corporateProxy property.

BTW @KianNH please excuse that newbie question here, but shouldn't this ja3Hash values also need to be added to the index.d.ts file?
yarn types:check keeps complaining on my project, and applying the following fix makes it happy:

diff --git a/index.d.ts b/index.d.ts
index 7dea8d3..073bb30 100644
--- a/index.d.ts
+++ b/index.d.ts

   score: number;
   staticResource: boolean;
   verifiedBot: boolean;
+  ja3Hash: string;
 }
 
 interface IncomingRequestCfPropertiesTLSClientAuth {

I'm a total newbie here, so please let me know if I'm missing something, but I have the impression that the index.d.ts needs to be updated after updating the overrides/.

[KianNH]

The types in the overrides directory are partial, and merged into index.d.ts when a release is made.

Thanks for your answer. The problem is that we cannot use the code from the repository (in CI for example) when it has not yet been released. For example, I currently have this in my package.json:

  "devDependencies": {
    "@cloudflare/workers-types": "https://github.com/cloudflare/workers-types/tarball/f5015a8d4b962460ea525ce5772a3296c223f9c7",
    [...]
  }

And that won't work. Do you have any idea how I could do?
