[WIP] Add symlink parameter

[Leo6Leo]

fixes #441

Summary of the change I have made:
Added an option to follow symbolic links when loading the registry in various parts of the codebase. The primary change is the addition of a follow_symlinks parameter, which is passed through multiple functions and structures to control this behavior.

Key changes include:

• Added follow_symlinks param as WeaverArg across SchemaResolver, SnippetGenerator, and ResolvedSemconvRegistry to enable optional symbolic link following during registry operations.
  -The WeaverArgs struct impacted various commands (check, generate, resolve, update-markdown, stats) to include and handle the follow_symlinks option.
• Modified SchemaResolver to configure walkdir::WalkDir with the follow_symlinks parameter and use the follow_links function.
• Modified the existing tests so that they will default to use follow_symlinks = false.

The ideal outcome would be:
After running the command

weaver registry generate -r ./semantic-conventions/model -t ./semantic-conventions/templates markdown -f

weaver will read symbolic linked folders under sementic-conventions/model and generate the artifacts.

PS: I try to raise this PR first to get some early feedback. As I am new to Rust and Otel, I am open to suggestions and feedback.

This is going in the right direction.

I suggest renaming this struct to CommonRegistryArgs and moving it to src/registry/mod.rs, as it will encapsulate the common arguments for all the registry subcommands. For global arguments (e.g., --debug), Clap already provides a mechanism. However, that mechanism cannot be used here because --follow-symlinks does not apply to commands unrelated to the registry.
