When a requirement contains "-class" in name, it breaks the mermaid graph.

When a requirement contains "-class" in name, it breaks the mermaid graph and in output html it shows

Syntax error in graph
mermaid version 8.6.0

This happens after version 1.4.0. In version 1.3.2 it works.

Below is a sample composer.json to reproduce this issue.

{
  "name": "test/issue",
  "description": "Composer Graph Issue",
  "require": {
    "php": ">=8.1",
    "php-curl-class/php-curl-class": "9.14.3"
  }
}

Generated mermaid code snipped from output html.

graph LR;
test__issue == ">=8.1" ==> PHP;
php_curl_class__php_curl_class-->ext_curl;
php_curl_class__php_curl_class-->|">=7.0"|PHP;
test__issue == "9.14.3" ==> php_curl_class__php_curl_class;

subgraph "Your Package"
    test__issue("test/issue");
end
subgraph "Required"
    php_curl_class__php_curl_class("php-curl-class/[email protected]");
end
subgraph "PHP Platform"
    PHP("[email protected]");
    ext_curl("ext-curl");
end

Error response from Mermaid Live Editor.

Error: Parse error on line 3:
...url_class__php_curl_class-->ext_curl;

I don't know the internals of mermaid so I don't have any clue why ..._class is tried to be parsed as a symbol class but just for the curiosity changing all occurrences to something like ..._classs successfully shows the diagram (Mermaid Live Editor)

Thank you for finding the issue.
I think I know how to fix it.

Just these days I'm going to do a release of the new major version.
I will add this fix to the release.
