About 10 mins after asking this question I thought of a different approach which is perhaps still a hack, but it avoids having to use the project directory name. I put the VSIX file in the .devcontainer/ directory, and then added a COPY command to the end of my Dockerfile thus:
COPY vscode-cds-1.1.4.vsix /tmp/
and could then specify this neutral path in the extensions property thus:
"extensions": [
"dbaeumer.vscode-eslint",
"/tmp/vscode-cds-1.1.4.vsix"
]
This works. Wondering if there's a better way though.

devcontainer.json has access to the following variables:
https://containers.dev/implementors/json_reference/#variables-in-devcontainerjson
So in your example it would be:
"customizations": {
"vscode": {
"extensions": [
"dbaeumer.vscode-eslint",
"${containerWorkspaceFolder}/vscode-cds-1.1.4.vsix"
]
}
}

Dev Containers tutorial
November 3, 2021 - Running VS Code inside a Docker container can be useful for many reasons, but in this walkthrough we'll focus on using a Docker container to set up a development environment that is separate from your local environment. You need Visual Studio Code installed. Docker is needed to create and manage your containers. Download and install Docker Desktop, or an alternative Docker option, like Docker on a remote host or Docker compliant CLI.
