fix: snippet tabbing, duplicates, and accuracy

[alexanderdombroski]

Fixes #105 and #87

Changes

• Merged duplicate snippets into the same, having multiple prefixes.
• Fixed '<%-' and '<%=' snippets having confusing descriptions
• Spaces -> tabs for code-block creating snippets (ie 'if')
• Added closing '}' to else statement, as you would never not need it.
• Added snippet choice insertion feature to choose 'let' or 'const' in for..of loop.

Because I completely redid the file, I merged a couple related PR's before I made my changes: PR 58 & 100

This PR consolidates and improves EJS snippets by removing duplicates, correcting descriptions, improving formatting, and adding new functionality. The changes address issues #105 and #87 related to snippet quality and usability.

Key Changes:

The prefix "<%" for the EJS Include snippet conflicts with multiple other snippets that also use "<%" as a prefix (EJS No Output, EJS For Loop, EJS For...Of Loop, EJS ForEach, EJS If Statement, EJS Else If Statement, and EJS Else Statement). This will cause ambiguity when users type <% and trigger the autocomplete. Consider using a more specific prefix like "ejsinclude" or removing this generic prefix from snippets where the specific prefix (like "ejsinc") is more appropriate.

Suggested change

	"ejsinc",
	"<%"
	"ejsinc"

The else if snippet is missing a closing <% } %> tag, unlike the other conditional snippets. This creates an inconsistency: the else statement (lines 128-130) has the closing brace, but else if does not. An else if block should also close its opening {, similar to how the if statement does.

Suggested change

	"\t$0"
	"\t$0",
	"<% } %>"

The snippet prefix listed here is ejsraw→, but there's also ejsunesc→ as a prefix in the actual snippet definition (snippets.json lines 24-25). The README should document both prefixes or clarify which one is the primary one. Currently, ejsunesc→ is missing from the documentation.

	| `ejsraw→` | `<%-` | `<%- %>` – Output **raw/unescaped** value (injects HTML) |
