[Update Request]: replace abandoned SamHocevar.WinCompose by ell1010.WinCompose

### What type of update are you requesting?

A change to the Package Identifier

### Current Package Identifier

SamHocevar.WinCompose

### Package Version

0.9.15.1

### Please describe the changes you would like to see

The project [SamHocevar.WinCompose](https://github.com/samhocevar/wincompose) is abandoned, see its [issue #543](https://github.com/samhocevar/wincompose/issues/543) for details. The latest release is from 09/2021 and for a long time, [only translations have been committed to the repository by weblate](https://github.com/samhocevar/wincompose/commits/master/), not involving any activity by the main developer who doesn't even respond to [any open issues](https://github.com/samhocevar/wincompose/issues).

The project [has since been forked](https://github.com/ell1010/wincompose) and is (more or less) actively developed -- the [latest release is almost a year old](https://github.com/ell1010/wincompose/releases), but [there's still commit activity and pull requests are being accepted](https://github.com/ell1010/wincompose/commits/main/).

So, can we please migrate `SamHocevar.WinCompose` to `Ell1010.WinCompose`, including the version upgrade to 0.9.15.1?

Thanks for your consideration!

No file or test is named in the issue. Start by locating the manifest for SamHocevar.WinCompose, then verify the requested migration to Ell1010.WinCompose and version 0.9.15.1 against the repository's validation checks; done means the package uses the requested identifier and version.
