docs: add Linux build dependencies for universal-ctags

[The-AarushiSingh]

Fixes #1633

Added the missing build dependencies required to build universal-ctags on Linux so the documented steps work on a clean machine.

---

Note

Low Risk
Documentation-only change to contributor setup instructions with no runtime or security impact.

Overview
Updates CONTRIBUTING.md so Linux developers can install universal-ctags v6.1.0 from source on a clean machine (fixes #1633).

The Linux section now includes Debian/Ubuntu (apt) and Fedora/RHEL/CentOS (dnf) package lists covering build tools and libraries (curl, gcc, autoconf, libseccomp, jansson, etc.) before the existing configure/make/install steps. The numbered development setup checklist is shifted by one step (3–11) after inserting the dependency block.
