[engsys] upgrade dev dependency typescript

Move to TypeScript 4.4

Major breaking issue: TypeScript 4.4 introduces a new flag called --useUnknownInCatchVariables. This flag changes the default type of catch clause variables from any to unknown.

we could use this flag to opt in as we are fixing libraries gradually.

This issue tracks the work to upgrade to 4.4 and use the flag to disable the check in the shared tsconfig.

Fix option 1:

try {
    executeSomeThirdPartyCode();
}
catch (err) { // err: unknown

    // Error! Property 'message' does not exist on type 'unknown'.
    console.error(err.message);

    // Works! We can narrow 'err' from 'unknown' to 'Error'.
    if (err instanceof Error) {
        console.error(err.message);
    }
}

Fix option 2:

try {
    executeSomeThirdPartyCode();
}
catch (err: any) {
    console.error(err.message); // Works again!
}

Personally I prefer option 1 over option 2 because option 2 just get rid of the compilation error but doesn't get any benefits from enabling the option..

I played with this a little bit and found that we will need to upgrade the api extractor first to v7.18.11 to play well with typescript@4.4. Otherwise, v7.7.11 will throw Error: Error parsing tsconfig.json content: Unknown compiler option 'useUnknownInCatchVariables'. This upgrade will update the api views for all packages so we will need to do it gradually. /cc @maorleger since he was interested in upgrading the api extractor before.

Thank you @deyaaeldeen for the heads up! It does sound like upgrading API Extractor is something we are bumping into a few times already. I spoke to @xirzec and @ramya-rao-a and we should just rip the band-aid out and do the upgrade. I'll take #9410 and will likely complete it early October - hopefully that works with your schedule?

@maorleger thanks a lot for doing this! That definitely works!

Most packages have been moved to v4.6. Codegen is also updated to use v4.6 in generated code. There are some track1 packages that remain untouched. We will keep them that way.
