Added CVE and EPSS to Chrome js

[chooko]

Hello Mitch,

We emailed briefly this morning about adding CVEs and EPSS to the extension. I decided to take a shot at it myself once I saw how the code was structured. Can you review?

(FWIW: I tried to add to the Firefox contexts as well, but when I realized they require a png it was a bit more than I wanted to bite off for this session.)

Thanks!!

@mitchmoser Looks like my checks have passed. Any luck that you can review this and push to next app update? 😊

Hi Brayden, I believe we had discussed tracking this request as an Issue rather than opening a PR.
The rationale is similar to Issue #15 with a request for a new search category that would consist of a single OSINT source.
I will close this PR for now and open an Issue to track and compile new sources for this category until there are enough sources that a new category should be implemented into the extension.
I am certainly open to answering any additional questions or taking feedback surrounding this.
