Update DPEL and MaterialX stages (#847)

### Pre-submission checklist:

*Please check each of these after submitting your pull request:*

* [ ] Are you including a `repo_url`? You need to pick the single best
GitHub repository for your project, not a GitHub organization.
* [ ] Is your project open source?
* [ ] Has this project been used successfully in the production of a
film, television program, animated content or other projects within the
scope of the ASWF. Was it designed specifically for the entertainment
industry?
* [ ] Is the project currently and actively maintained (e.g., accepts
pull requests, replies to issues, has been tested against / builds
properly with the compilers for this year's VFX platform)?
* [ ] Have you picked the single best (existing) category for your
project?
* [ ] Does it follow the other guidelines from the [new
entries](https://github.com/AcademySoftwareFoundation/aswf-landscape#new-entries)
section?
* [ ] Have you added the SVG for your logo to `hosted_logos` and
referenced it in the entry in `landscape.yml`?
* [ ] Does your logo clearly state the name of the project/product and
follow the other logo
[guidelines](https://github.com/AcademySoftwareFoundation/aswf-landscape#logos)?
* [ ] Does your project name match the text on the logo?
* [ ] Have you verified that the Crunchbase data for your organization
is correct (including headquarters and LinkedIn)?
* [ ] ~5 minutes after opening the pull request, the CNCF-Bot will post
the URL for your staging server. Have you confirmed that it looks good
to you and then added a comment to the PR saying "LGTM"?

               In order to encourage development and research that addresses the true scale, scope and requirements of computer graphics film production, the
               Asset Repository seeks to publish and maintain curated exemplars of the data sets used in our industry. Research projects and commercial
               development projects often have trouble obtaining input datasets with full film complexity, and that are licensed to allow publishing research
               results and software demonstrations. Disney’s Moana Island is a prime example of what we want to encourage, but in addition to 3D scene data,
               assets could also be images, image sequences, volumetric data, animation rigs, edit decision lists, etc.
