Improve Tool Filter docs

Current Docs: https://docs.gitlab.com/ee/user/application_security/vulnerability_report/#tool-filter

With all the different types of Tool filters, perhaps there is an opportunity to improve our docs 💪

Group	Security Control (Instance)	Project	Project (with custom vendors)
tool_filter.vue	tool_filter.vue	tool_filter.vue	tool_with_scanner_filter.vue Not relevant to this issue per se, but I intend to rename this back to tool_with_vendor.vue

Demo

• Project with custom vendor ex 1 > https://gitlab.com/gitlab-org/govern/demos/sandbox/minac/test-remediations/-/security/vulnerability_report
• Project with custom vendor ex 2 > https://gitlab.com/gitlab-examples/security/security-reports/-/security/vulnerability_report
• Project (no custom vendor) > https://gitlab.com/gitlab-org/security-products/tests/webgoat.net/-/security/vulnerability_report

Types of Tool filter

• a. tool_filter.vue = filters the vulnerabilities by report type. The report types are hard-coded data and are the same no matter what group, instance, or project.
• b. tool_with_scanner_filter.vue = filters the vulnerabilities by scanners, only available if there are custom vendors. As these are setup by the users and custom in nature, the data can vary across different projects.
