High severity CVEs in the rest component

Nobody has claimed this yet.

### Describe the bug

There are several CVEs posted against the version of undici used by the version of openapi that this project is using. As of the past few days some high severity items came in, so this probably should be looked at as its causing audit failures.

CVEs:
Undici has an unbounded decompression chain in HTTP responses on Node.js Fetch API via Content-Encoding leads to resource exhaustion - https://github.com/advisories/GHSA-g9mf-h72j-4rw9
Undici has an HTTP Request/Response Smuggling issue - https://github.com/advisories/GHSA-2mjp-6q6p-2qxm
Undici has Unbounded Memory Consumption in WebSocket permessage-deflate Decompression - https://github.com/advisories/GHSA-vrm6-8vpv-qv8q
Undici has Unhandled Exception in WebSocket Client Due to Invalid server_max_window_bits Validation - https://github.com/advisories/GHSA-v9p9-hfj2-hcw8
Undici has CRLF Injection in undici via `upgrade` option - https://github.com/advisories/GHSA-4992-7rv2-5pvq

I am not sure what a good fix is here because the @openapi-contrib/openapi-schema-to-json-schema package that rest is relying on hasn't been updated in 3 years, so it is probably no longer maintained.

### Additional information

_No response_

### Reproduction

n/a

The issue names @loopback/rest, @openapi-contrib/openapi-schema-to-json-schema, openapi-typescript, and undici; start by tracing that npm dependency chain and running the reported audit. Done means the listed high-severity advisories are addressed without relying on the stated breaking upgrade to @loopback/rest@7.0.1.
