Project Infra: Image build repository(s) for utilities that are used during local development (like yamllint)

[adrielp]

After discuss in the Semantic Conventions SIG with @jsuereth & @lmolkova it seems like a good idea to have a repo (or repos) that are maintained and build tooling images to be used by the various different groups. One notable example is that of yamllint. In many of the workflows yaml files are linted through this utility which is installed through python at a specific version. As the SemConv group has standardized on mostly using container images through the make rules to handle this, building and keeping images up-to-date would be ideal.

Also discussed this with @austinlparker & @trask in the infra SIG.
