fix: address edge case when getting DIDDoc component

[nickreynolds]

What issue is this PR fixing

fixes #1364

What is being changed

The getDIDComponentById function in did-resolver/src/resolver.ts is modified so that it correctly finds the result when the didUrl passed in is a keyID without the DID prefixed to it, but the resolved DID Document lists the key with the prefix.

Quality

Check all that apply:

• I want these changes to be integrated
• I successfully ran pnpm i, pnpm build, pnpm test, pnpm test:browser locally.
• I allow my PR to be updated by the reviewers (to speed up the review process).
• I added unit tests.
• I added integration tests.
• I did not add automated tests because I am unable to reproduce this error in unit tests, and I am aware that a PR without tests will likely get rejected.

Details

it's possible that this is not the ideal solution and the proper fix for the bug is upstream from this function

Looks good.
It would be nice to add a test case for this
