## What is the current behavior?
`@stencil/react-output-target` is pinned to exactly `1.5.0` in
`core/package.json` and `packages/react/package.json`. This was a
defensive pin after `1.5.1` shipped a regression that dropped the
`Partial<C>` wrapper from `StencilProps`, which broke everything in our
react apps by [requiring all props to be
defined](https://github.com/ionic-team/ionic-framework/actions/runs/25007199736/job/73233599812?pr=30831).
Exact-pinning meant we couldn't pick up future patches in the `1.5.x`
line.

## What is the new behavior?
Both `package.json` ranges move to `^1.5.2`. Upstream fully reverted [PR
#788](stenciljs/output-targets#788) in
[`1.5.2`](https://github.com/stenciljs/output-targets/blob/main/packages/react/CHANGELOG.md),
so the generator emits `Components.${tag}` again and the runtime
restores `Partial<C>`. Regenerating
`packages/react/src/components/components.ts` against the `1.5.2`
generator and running prettier produces a file byte-identical to the one
committed under `1.5.0`, so the published shape is unchanged.

## Other information

<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->

The original break, the upstream conversation, and the rationale for
staying on the `1.5.x` line (rather than taking the new "errors on truly
required props" behavior) are all in the [PR #788
thread](stenciljs/output-targets#788).
