Update vcpkg baseline to latest released tags/2022.10.19

This is now in-sync with Embedded C as well.

Follow-up to #4036

On Ubuntu 18, we are facing the same issue as the one in Embedded C:
Azure/azure-sdk-for-c#2400 (comment)

The build machines seem to have already defined VCPKG_ROOT env var and have a clone of the vcpkg repo at the particular commit which is different than the baseline we are trying to establish:

fatal: path 'versions/baseline.json' exists on disk, but not in '94ce0dab56f4d8ba6bd631ba59ed682b02d45c46'

This may be fixed by updating vcpkg to the latest master via `git pull` or fetching commits via `git fetch`.

You can use the current commit as a baseline, which is:
    "builtin-baseline": "ce99c947b64ea3c0e274e18cc3035ca727681089"

The vcpkg tool change to ignore the VCPKG_ROOT environment variable when we detect that the binary is within a valid root went out in tool release 2022-10-12, which was included in catalog release 2022.10.19.

So, the reason why this was failing only on Ubuntu 18.04 before was because the build machine images define VCPKG_ROOT and VCPKG_INSTALLATION_ROOT, with a pre-installed copy of vcpkg at the commit sha that is older than what we need (coincidentally just a day older, Oct 18):
microsoft/vcpkg@ce99c94
https://github.com/actions/runner-images/blob/6ef9c61220d9712317731cbdaa53bb0b25e73f94/images/linux/Ubuntu1804-Readme.md#package-management

Vcpkg (build from master <ce99c947b>)

The CI was passing on other build machines (such as in Ubuntu 20), even though they too define VCPKG_INSTALLATION_ROOT (but not VCPKG_ROOT) because it has a newer vcpkg commit sha (from Oct 27), which contains the vcpkg baseline we are looking for (i.e. tags/2022.10.19):
microsoft/vcpkg@48cc0c7
https://github.com/actions/runner-images/blob/6ef9c61220d9712317731cbdaa53bb0b25e73f94/images/linux/Ubuntu2004-Readme.md#package-management

Vcpkg (build from master <48cc0c71e>)

We, now, no longer rely on VCPKG_ROOT or VCPKG_INSTALLATION_ROOT environment variables set or look at the system-level vcpkg clone, and just clone the vcpkg repo locally, within the sub-directory of the azure-sdk-for-cpp repo.
