chore: Fixes Some Terminology to Avoid Confusion.

[Spiral-Memory]

Issue(s)

Fixes "Basic Terminology"

Acceptance Criteria Fulfillment

• In the help section, since we can't create a new page as notion doesn't allow that but rather a subpage in the existing page, so the term "create page" is misleading. Therefore, it has been fixed.
• When a database is selected, there is an overflow option to change the database. However, this is misleading, as with that option, we simply go back. Now, we can select both a page and a record, so Change Database has been changed to Change Selection.
• In the Create Page or Record section, we select a Parent page from dropdown in which a new page has to be created, so that label has been added.
• We can't add the title of the database directly without selecting a database first, so the placeholder text has been changed from Enter title of page or Record to just Enter title of page.
• When a new Record is created, it doesn't provide proper information to the user like what has been created, what is the title, and in what database, so that has been added.
• Added a help message for command \notion view.

Proposed Changes (Including Videos or Screenshots)

This is a very basic terminology fix to avoid confusion. I am not creating an issue for it; I just thought of making these changes. If @Nabhag8848 you also feels that these need to be addressed, you can review the changes. Otherwise, you can close this PR, as it is not a substantial change at all. If you feel this needs to changed but not a separate PR, you can let me know that too.
