🐛Change Timezone in Docker

**Describe the bug**
The Docker container has tzdata installed and timezone set, but cloudflared logs show ETC standard time

**To Reproduce**
Steps to reproduce the behavior:
1. Use the following Dockerfile
```
# Stage 1: Build container

# Use a specific Golang version and Alpine Linux as the base image
FROM --platform=linux/amd64 golang:1.20-alpine AS build

# Set the working directory for the build
WORKDIR /src

# Install necessary dependencies for building
RUN apk --no-cache add git build-base curl jq

RUN apk --no-cache -U add tzdata
RUN ln -s /usr/share/zoneinfo/Europe/Berlin /etc/localtime

# Fetch the latest release version using GitHub API
RUN VERSION=$(curl -s https://api.github.com/repos/cloudflare/cloudflared/releases/latest | jq -r .tag_name) \
&& git clone https://github.com/cloudflare/cloudflared --depth=1 --branch ${VERSION} .

# Build the cloudflared binary for Linux amd64
RUN GO111MODULE=on CGO_ENABLED=0 GOOS=linux GOARCH=amd64 make cloudflared

# Stage 3: Runtime container
FROM alpine

# Set the working directory in the new image
WORKDIR /

# Copy the built cloudflared binary and required files
COPY --from=build /src/cloudflared .
COPY --from=build /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/

# Copy curl binary from a docker image
COPY --from=ghcr.io/tarampampam/curl /bin/curl /bin/curl

RUN apk --no-cache -U add tzdata
RUN ln -s /usr/share/zoneinfo/Europe/Berlin /etc/localtime

# Set environment variable for the cloudflared origin certificate
ENV TUNNEL_ORIGIN_CERT=/etc/cloudflared/cert.pem

# Specify the entry point and default command for the container
ENTRYPOINT ["/cloudflared", "--no-autoupdate"]
CMD ["version"]
```
2. And the following docker-compose file
```
version: "3.9"

services:

tunnel:
build:
context: .
dockerfile: Dockerfile
image: cloudflared:custom
container_name: tunnel
restart: always
command: tunnel --metrics 0.0.0.0:3333 run
environment:
## Set timezone
TZ: ${TZ}
healthcheck:
test: ['CMD-SHELL', 'curl --fail http://localhost:3333/ready || exit 1']
volumes:
- ./cloudflared:/etc/cloudflared:ro
- /etc/timezone:/etc/timezone:ro
#- /etc/localtime:/etc/localtime:ro
networks:
- cftunnel-transport
```
4. Run `docker-compose up --build` in the same directory

**Expected behavior**
Using docker-compose logs in the directory the log timestamp should be using the time set in the alpine container

**Environment and versions**
- OS: Linux
- Architecture: amd64
- Version: 2023.10.0
