Use Dependabot to check Dependencies in Bash scripts and Dockerfiles - dependabot

Question

I would like some notifications from Dependabot when new versions are available. These are my two scenarios:
#1 I'm starting a docker container in a bash script like this.
local DOCKER_IMAGE="hashcorp/terraform:1.3.6"
docker run --rm \
--volume /etc/passwd:/etc/passwd:ro \
--volume /etc/group:/etc/group:ro \
--user "$(id -u):$(id -g)" \
--volume /etc/timezone:/etc/timezone:ro \
--volume /etc/localtime:/etc/localtime:ro \
--volume "$(pwd):$(pwd)" \
--workdir "$(pwd)" \
--env "GITHUB_TOKEN=$TOKEN" \
--env "TF_VAR_bw_client_id=$BW_CLIENT_ID" \
--env "TF_VAR_bw_client_secret=$BW_CLIENT_SECRET" \
--env "TF_VAR_bw_password=$BW_MASTER_PASS" \
"$DOCKER_IMAGE" "$#"
For other Dependencies like Docker Images I use Dependabot to raise a PR when I should update my base image. Is there a way to have Dependabot inspect bash scripts like the above snippet as well? I'd like a notification when there is a new terraform version.
#2 I'm installing Bitwarden CLI into a custom terraform image (needed for the Bitwarden Provider. This works fine. But since I pin the Bitwarden CLI version in my Dockerfile I would like Dependabot to raise PR for the Bitwarden CLI as well.
FROM hashicorp/terraform:1.3.6
LABEL maintainer="sebastian#sommerfeld.io"
# Install basics
RUN apk update \
&& apk --no-cache add curl=7.86.0-r1 \
&& apk --no-cache add unzip=6.0-r13
# Install Bitwarden CLI + dependencies
ARG BW_VERSION="2022.11.0"
RUN apk --no-cache add libc6-compat=1.2.3-r4 \
&& apk --no-cache add gcompat=1.1.0-r0 \
&& apk --no-cache add libgcc=12.2.1_git20220924-r4 \
&& apk --no-cache add libstdc++=12.2.1_git20220924-r4 \
&& rm -rf /var/cache/apk/* \
&& curl -sL https://github.com/bitwarden/clients/releases/download/cli-v${BW_VERSION}/bw-linux-${BW_VERSION}.zip -o bw.zip \
&& unzip bw.zip \
&& chmod +rx bw \
&& rm bw.zip \
&& mv bw /usr/local/bin
Is it possible to use Dependabot for these scenarios as well?
