feat: Add TencentOS Server to supported distributions

[guoningzhang20]

Summary

The Docker convenience install script (install.sh) does not recognize TencentOS Server (ID=tencentos) as a supported distribution. When run on TencentOS, the script exits with ERROR: Unsupported distribution 'tencentos'.

TencentOS Server is a RHEL-based distribution maintained by Tencent Cloud, fully compatible with the CentOS/RHEL ecosystem. It uses dnf as its package manager and can use CentOS Docker repositories directly.

Changes

Modified install.sh to add tencentos support in three places:

1. Version detection (case "$lsb_dist"): Added tencentos alongside centos|rhel to correctly extract VERSION_ID from /etc/os-release.
2. Package installation (case "$lsb_dist"): Added tencentos alongside centos|fedora|rhel to enable the RPM-based installation path.
3. Repository URL mapping: Added a check to map tencentos to the centos Docker repository, since Docker does not maintain a separate TencentOS repository.

TencentOS Server Info

• OS Release: ID=tencentos, ID_LIKE="tencentos", PLATFORM_ID="platform:el9"
• Package Manager: dnf (yum compatible)
• Ecosystem: Fully RHEL/EL9 compatible, uses CentOS Docker repositories
• Official site: https://cloud.tencent.com/product/ts

Testing

Verified on TencentOS Server V4.4 (x86_64) that the modified script:

• Correctly identifies TencentOS as a supported distribution
• Maps to the CentOS Docker repository for package installation
• Successfully installs Docker Engine packages via dnf
