Bump jQuery to v3.7.1 and jQuery-UI to v1.14.2 (#2476)

## Context

- jQuery is a bit outdated (not a big deal)
- jquery-ui is outdated, there exists CVE (and we're probably not
vulnerable)
- the `"components-jqueryui"` package is unmaintained: in case of a
vulnerability, dependabot won't trigger an update.

## Proposed solution

- Bump jQuery to the latest minor version (3.7.1)
- Migrating to version 4 is out of scope: version 3.X is still benefits
from security updates ([source](https://jquery.com/support/)) and
`bootstrap-datepicker3` requires jQuery < 4 as of today.
- Migrate to the `"jquery-ui"` to take advantage of the depandabot
updates (probably the best motivation behind this PR).

Side-notes:
- `_respectSize` [is monkey-patched
here](https://github.com/gristlabs/grist-core/blob/c9155e0f9a52d5f03b5eece37c93903657af18df/app/client/components/viewCommon.js#L12),
but the original method has been untouched since version 1.2.0 (you may
check the associated commits):

- also no call to external function except `this._isNumber`, also
untouched.
